1973 Cobalt Mercruiser 165hp Survivor Part 2 Solving some issues

[@k6outdoors]

Nice work, that water pump had seen better days! Good to see the old girl chewing through the water.

[@Michaelsbackyardmarina]

we got ourselves a runner for sure, thanks for watching and commenting Mr. K6

The split gearbox o-ring of death. Make sure you use OEM. Part of the reason I moved to outboards. That red o-ring will cause many headaches. No cheating on that one!! Loving the Mercruiser stuff.

thanks for the tip and for watching

Thank you for all the info I just bought a project boat A 1976 Aristo Craft

[@timconklin8489]

Michael just a suggestion for changing the oil the is a device that you attach to your drill and pump out the oil from oil pan. The device has a tube that goes into the dipstick and another one that will go into another bucket for the used oil. I hope this helps. Thanks Tim

[@Michaelsbackyardmarina]

Good tip! I actually have a pump for just such a thing, this one has room for a pan so that's what I used this go round, thanks for watching.

[@johnmccrea8106]

It really is! Thanks for watching.

I sure hope so, thanks for watching and commenting.

Mike Snap on makes a great screwdriver specifically designed to fit the drain screws. I got mine on Amazon.

great video michel

[@Michaelsbackyardmarina]

Glad you enjoyed it, thanks for watching.

I use PVC PIPE 2.5” cut out 1/4 to 1/3 out ( enough to go over the ram ) raise all the way up then measure the length and cut PVC to fit and no need for the strap ! Usually the check valves start to wear out which causes the loss of pressure to hold the lower unit up . Or air in the line like brakes on a car . Remember that boat weighs a lot and a 165hp is doing great at 38mph ! I have a Crestliner by AMF Tri-hull if you want it , The Forester is gone ,my grandson gave it to his step dad .

[@Michaelsbackyardmarina]

Great tip! After reading your tip this morning I went out and cut a piece and made that is a genius idea, I will feature it in an upcoming video. Is it ok if I mention your you tube name?

[@davekimbler2308]

@@Michaelsbackyardmarina yes go ahead , I really like that boat ( usually i don’t like Tri-Hulls ) and sounds fantastic !

[@henryherber1973]

what app did you use for the speed on the water? I have a '71 Searay SR190, same motor, all merc outdrive. thanks for the rebuild video, need to do work myself this coming season. Tired of this Michigan weather!

[@timconklin8489]

Nice work on the stren drive. How much did have to adjust the steering stag? Thanks Tim

[@Michaelsbackyardmarina]

looking at it from the top down, I went full clockwise on the adjustment.

[@vnc7345]

That little comment you made about liking "big biminis" was hilarious (1:05:15). Should we start calling you "Sir Fix-A-Lot" now?

[@gearheadgregwi]

My guess on the drooping issue. Emergency vent screw on pump isn't holding air pressure. If it was a hydraulic line, you'd be pissing fluid into the bilge.

[@Michaelsbackyardmarina]

I'll look into that, Thanks for watching

[@anthonylatronica5108]

Mike look art the spec for WOT it should be about 5200. You should prop to hit the WOT rpm.

[@Michaelsbackyardmarina]

I have the spec book right in front of me and for the 165 hp WOT 3900-4300 rpm, you run this inline 6 at 5200rpm and it won't last too long. Thanks for watching.

[@JL-hy7ve]

Great video but you should not use grease on rubber, OMC recommends using dish soap (water soluble), grease will degrade the rubber.

[@Michaelsbackyardmarina]

Thanks for the tip!

[@gearheadgregwi]

🤣🤣🤣 I put my 1973 800 Mercury together Monday. Just got lobster sunburned. In Wisconsin, where the leaves are already changing color.

[@Michaelsbackyardmarina]

Gotta watch that sun burn, some of the more painful pains for sure. Thanks for watching.

[@richardcranium5839]

damn that terrain is flat! do you get new lakes everytime it rains hard?? lol

[@Michaelsbackyardmarina]

I wish, I would have more fishing and boating closer to me. LOL

[@robertrabhudsonhornet5869]

Being its so hot way not put the boat in the shade. That is a nice looking boat for its age

[@Michaelsbackyardmarina]

convenient shade is sometime illusive around my place. Thanks for watching and commenting

[@pablos6.060]

I think an aluminum 17p would be better and rev around 4,200-4,500. I have a Merc 5.0 in a 20 ft and tried 19, 17, and a 15p 4 blade works best for me.

[@Michaelsbackyardmarina]

thanks for the tip and thanks for watching

[@michaelmurrietta2263]

Make sure you can run close to max rpms trimmed out or you are gonna need a valve job

[@Michaelsbackyardmarina]

It runs at the bottom of the WOT range trimmed out. Thanks for watching

[@geraldkoth654]

@@Michaelsbackyardmarina The gurus say run at the TOP of the WOT range or you are overloading the engine and will have problems. I have seen two ranges, 4000 to 4500 and 3900 to 4300.

[@michaelmurrietta2263]

Wrong rear thrust washer for a turbo next time glue oring into bellow housing 142 thermostat marine only max rpms 4600 find out what gear ratio is in that aftermarket lower and valve body on trim reservoir is internally

[@Michaelsbackyardmarina]

Dang, thanks for the information dump, it really is much appreciated. Thanks again for watching.

[@geraldkoth654]

That is a replacement outdrive. Some get lots of use out of it, some not so much. Here are some calculations of RPM Propeller Pitch and slippage. A good fit prop should have about 10 to 15% slippage. The Original prop Engine RPM Gear Ratio Pitch MPH 100% MPH 52% 3900 1.65 17 62.8 34.5 The Alternate prop Engine RPM Gear Ratio Pitch MPH 100% MPH 55% 3900 1.65 20 77.6 38.8 So that combo you have is just stirring up a lot of water and not providing a lot of forward thrust. The pitch is far too great. You may even be cavitating with that much slippage. This combo is in the proper slippage range Engine RPM Gear Ratio Pitch MPH 100% MPH 85% 4300 1.65 13 52.9 45.0

[@Michaelsbackyardmarina]

I will soon find out how good they are, I'm going to install another one on my Starcraft, thanks for watching

[@michaelmurrietta2263]

And by the way find some shade first

[@Michaelsbackyardmarina]

I need to some shade for sure. I need a big climate controlled warehouse to hang out in.
