Mercury 2 Stroke V6, 60mph for $500, is it possible???

Welcome back to my channel! There was an amazing response to the first episode in this series that covers the design and development history for the Mercury 2 Stroke V6 Outboard, and I'm proud to present episode 2 where I bring home another project boat.
Why?
Well, it had a running Black Max XR2 V6, and it was $500 so I pretty much had to buy it, and my girlfriend is super cool. I'll go over the Cee Bee Avenger's condition, show you how to check the transom, talk about the 150hp XR2, try to get that started, and then go inside to show the current status of the Porsche 911 project car, and the Mercury 200hp V6 BlackMax with CLE gearcase for the SST project. Stay tuned, and thanks for the support! Cheers!

I just came across your videos yesterday. Saw your 1000 muscle boat. Then subscribed. Love your content! I own a body shop and have been restoring classic vehicles for decades. Im now getting into boating. I just came across a really wild 73 Schuster Tahiti bubble deck jet boat with brand new jet drive for 1200. Gold flake and burgundy with brown diamond tuft seats. Looks strait out of the 70’s! It just needs a good polish (possibly a repaint) and motor. My GF and I are very excited about getting into this project. You folks are awesome! Very inspirational.

[@ADDvanced]

Thanks Johnny! Boating is more fun than cars when the weather is hot, for sure! Post videos if you pick it up!

[@ryancollins2483]

The beeping is either an overheat alarm coming from one of the sensors in the heads grounding out either correctly or due to bad wiring, or it’s your oil injection system. Most guys delete theirs by ordering a cheap blockoff plate, removing the oil pump shaft and wiring, and premixing 50:1 or 40:1 for 6000+ rpm running. Most of the oil injection gears connected to the crankshaft were plastic and would inevitably shear off at an inopportune time leaving you without oil at high RPM and cook your motor very quickly. I just premix my XR4, piece of cake.

[@MrMaxpower76]

I concur cheers

[@ADDvanced]

K, I'll pull the cowl and poke around, but it wasn't beeping when I was running it on muffs. Going to do a waterpump and gearcase oil, fuel filter, and I'm not sure what else, then see what it'll do on the water. I'm not sure how the choke systems work on these yet either; I didn't see a mechanical lever on the controls like I remember. Yeah, I was planning on doing premix on the SST, but for this Avenger, I'm not sure yet. Are there higher quality gear replacements available somewhere? Not mixing is pretty nice.... ngl. It's just one more variable.

[@ryancollins2483]

@@ADDvanced you push the key in to engage the choke. It’s usually a shutter valve that closes over the carb throats. Some models have an enrichment system instead but it works just the same way. If you’re going thru the motor to verify the maintenance/health do the following: - compression test - spark plugs - inspect plug wires - replace poppet valve - replace impeller and housing/gaskets - replace any questionable fuel/vacuum lines - replace gearcase oil -remove and test the thermostats to make sure they open at 140 ish degrees The motor will NOT pee until the heads reach the temp in which the thermostats open. This is normal and expected. Don’t put your hand in the pee stream unless you want to burn it.

@@ADDvanced can't wait to see how she runs for ya!! *Unfortunately with the garbage gasoline we get these days, good, clean carbs can be gunked up very quickly if left to sit for even just a couple of months. One thing I recommend to all of my customers and fellow boaters is to run fuel stabilizer in the gas, ESPECIALLY if you might not get to run the motor again for a while! Just putting enough stabilizer in the tank at least a mile before you put the boat on the trailer will keep the fuel fresh in both the carbs and fuel system as well as the gas tank too! Hope that helps keep your motors in good running condition!

As someone already commented, the 150 XR2 was the 2.0 Liter hot rod Merc that was targeted for the Bass fishing competitions. Apparently, the competitions accepted motors with up to 10% over the stated HP and hence the hopped up version. I had an XR2 on my 17' Glastron CVX and saw about 60 MPH. As for prop advice for your SST, I'm running a 24P Trophy, four blade on my 20.2 Lavey Craft Sebring (similar mod-VP hull), Merc 200XS with a sporty lower (1:87). The Trophy is a good all around prop and you may be able to get away with more pitch....

A couple of things. The poppit valves changed a lot over the years. You must get the exact one for your year. They open at about 2000RPM, bypassing the thermostats and allowing lots of cooling water to circulate. Only a couple of years of Merc V6 motors had accelerator pumps. Not sure if your has it, but pumping the throttle before starting is useless. Hold the choke down, with a little bit of throttle and crank until she starts. A lot of folks recommend removing the oil injection and idle stabilizer. The oil injection is driven off the crankshaft with a plastic gear. These can fail. Run 50::1 premix instead. I have a 16' Avenger and run a '93 Merc 135HPV6. Set up correctly she will run in the mid 60's

cant seem to reply so Ill reply here. Didnt have a speedo and no GPS back then but I've had a lot of boats and my guess would be about 70 with good water and just the right trim. A friend had a Ebko Stinger Tunnel boat with the same engine and I could just ease away from him a mile or 2 per hour. His boat was heavier and that tunnel is a faster hull. Good times.

[@davidmclendon7244]

I stand by my statement. Avenger, Baker, Stroker all had air entrapment hulls. As a matter of fact, Avenger, and Baker were identical to the Sleekcraft. I bet Nescher copied Avenger and Baker. Avenger was all hand laid with full stringers and 13/4" transoms. Bob Brown built the Avenger's in Lynwood California and retired a few years ago when the boating industry was suffering through an economic slow down in the late 90"s. I believe Mr. Brown was the tech. advisor for many boating magazines. His boats were outstanding.

[@davidmclendon7244]

The valley in the deck was to add strength to the deck, it was unique only to the Avenger ski boats. The Bubbledeck were first seen in the Sanger flatbotton race boats. The design was copied by almost all of the performance boat builders on the west coast in the 70's and 80's. Now it is almost impossible to buy a new boat under 30 feet on the west coast. If you take your time on your Avenger you will have a real prize on your hands. I think a you will be surprised what you will be able to sell it for.

[@ADDvanced]

Some of sleekcrafts earlier, smaller designs might have been copies, I'm not sure, there was so much happening but I could ask Debbie Nescher about it. I don't know if she'd remember the super early days tho, I don't think she was around yet lol. That said, I don't think the Aristocrat/SST hulls were copies of anything; the curves are a lot different than other boats, it was even patented.

I agree. I was a Mercury dealer back in 1985/86/87 and pretty sure the XR2 came out in 1986. Putting a new impeller in is pretty basic...but i have found that often running a V6 on 'muffs' doesn't give the engine enough flow/pressure , if you can back it down a ramp or run the engine with the gearcase in a tank of water you will probably get a better flow of water out the 'pee' hole.

It has a float switch in the upper tank that turns on the beeper for low oil . You still have enough to get back that way.

Wondering if you're figured a way to work your trim on the sleek with a foot throttle? Put a stationary foot pedal opposite of throttle with 2 up switches in case one fails, mount down switches in the steering wheel 3 or 4 if possible.

Funny cause I have been trying to pull the money together to get either a Laser 380 Ray or an LTV for a while now -- I actually have a Laser 380 lined up in what looks like pretty good condition, but I'm sure there's some wet wood at the least. But I just have wanted one since I went for a drive in a 380 copy(StarCraft Eagle believe it or not!) That did an easy 80mph with a modded gt150 OMC on the back of it!

@@ADDvanced I would get about 75 just with me only in the boat. That is without surface driving the the prop. I had the stock water intake. Keep in mind that if you Jack up your manual Jack plate you will have an extreme tendency to turn right with dual cable steering system. Make sure that the plug on the back of the boat will drain the sub Floor. I did find water in my sub 4 and had to install a second plug just below the original.

Also when it comes to the prop pitch I would start around a 21p for 200hp and work your way up. My rule of thumb has always been if you hit a rev limit you need to up the pitch. My current setup is a 23p 4 blade on a 225 h.o. evinrude on a 21ft 87 checkmate starflite which get me right around 70mph and I never see the limiter. Obviously there are more factors at play (weight, hull design, 3 blade or 4) but it might be a starting point, food for thought. Cheers.

[@bassassin2ohseven584]

It may have an auxiliary oil tank under the cowl that the level sensor is bad in causing the beep. Generally 4 blade props are for better hole shot and handling which with a 150, a 16 foot boat shouldn't have trouble getting on plane. Experimenting with pitch/diameter and going to a 3 blade, that boat should easily get into the mid to high 70's I would think. Growing up I rode in an Avenger jet boat with a big block Ford and I know a guy currently that has probably a 19' with a 200 Merc that is just sitting here in Maine. Definitely cool boats and fast!

[@ianbond3982]

Just some tips for you. On the Avenger, dont run that jacking plate too high as that Merc 150 sti has a 'normal' water pick up on the leg, too high & you'll loose water cooling. The other Merc has the Speed master or Sport master leg & wter pick up is at the front, but just below the point on the 'torpedo' (for the prop shaft) so you can run that till approx 1/2 way horizontally on the torpedo! 3 blade vs 4 blade? 4 blade for hole shot, more 'grip' for social skiing, etc. 3 bladers come in that many variations these days, but if you are looking for just speed, then look into racing props, if you intend to run the prop as a surface piercing type, using the hyd jacking plate, then, then in old school terms, used to be called a 'chopper'. If you are running the SST Merc on the tunnel hull, then I estimate you'll be looking at around 27" pitch, but just guessing, as each hull motor combo is different. I run a Labsport 1700 with a 2001 model, 3 litre 200hp on it, with a jacking plate & 23" pitch 3 blade, & I have to be careful as rpm limiter cuts in because there isn't enough load on the prop to hold the revs down at wide open. I mainly social ski with it, but it is an ex ski race boat, & if I was going to race it, I would start with a 27" 3 blade surface piercing prop. Currently my boat does approx 75 mph, (23" prop) trim & jacking plate set for top speed. Most of the race boats do about 100 mph towing 2 skiers on 200' ropes. Just type in Labsport 1700 on KZbin to see them racing, & yes I'm in Australia & Labsport is an Australian hull. Hope that helps

The oil tank is baffling ,to me anyway. My first thought was late 80s on the motor. But I didn't think oil injection came around until 90 something. Anyway, if it starts and runs decent then it's begging for an over the hub chopper around 26" pitch to start. May be sketchy without a pad at much over 60. May start getting it for weight savings. Who needs a floor? As far as the Sleekcraft, a good 26 may be in order there also. The hydraulic jack plate will let you get away with a little steeper prop on take off but I can promise you a prop is everything when it comes to top end. A good lab finished round ear will give you plenty of bow lift and although some bash them I'm a big fan of a Hill chopper. Drop about 800 to a grand on one and it won't disappoint.

If I suspect a fuel pump or other issue I often run the motor off of a pump up garden sprayer. " Here comes the danger police" but carefully.
