What kind of tilt trim is that it looks easy to install on a motor without it

[@THISOLDOUTBOARD1]

Hey. Thanks for watching and commenting. Its OMC T & T unit produced from the early 70's till the late 80's. Yeah with some parts swapping it may work on a lot of motors. Thanks again & Stay tuned !

[@danielrobert7181]

Hey, my guesstimations (loosely based on my "Mercury Big Foot" experience) are that the larger lower gearcase just provides you with a beefier unit. The added drag due to the larger case and prop won't be significant at speeds under 50 mph. The larger diameter of the prop shouldn't impact much but, as you are pushing a light and easy planing hull (vs a pontoon), the higher pitch will move more water (whithout dampening the motor's acceleration curve) and provide faster holeshots.At equal wot rpm, you also ought to get a few extra mph. But then, I could entirely be wrong. LOL! Stay safe and be merry !

[@THISOLDOUTBOARD1]

Hahaha It sounds good! Thanks again !

[@louisianag]

Man what do you think would be the right prop for my 1998 70hp Johnson I have a 13x19 right now and I'm at 37-39 mph at 5600 rpms but I have to trim up really high to get those rpms ranges my rooster tail is above my motor some. Should I drop to a 13.25x17 pitch to get those rpms up. I had a 14x17 which was the biggest diameter you could fit and at 6000 rpms I was at 35.5 mph.. I just feel like I'm lugging my motor bad with this 13x19 All are aluminum props by the way on my 1999 Lowe 17 bass. Online it says for the motor the WOT range is 4500-5500

[@THISOLDOUTBOARD1]

Hey. I'm in the same boat. What Prop would be Best? Hahaha. We were discussing it just tonight. Captain Mark, my neighbor said, You could go through 20 props before you find the right combination. It gets very mathematical. I, personally never worried to much about it dealing with the smaller outboards. If I needed a prop I would go with the standard size. But now, I'd like to know! Hahaha. I could do 3 pages on the subject but I won't. Spare you and myself! Anyway, do as much homework on it as you can, it's all on the interweb. Just another pain in the azz! Thanks for watching and commenting. Stay Tuned !

[@KyleC0430]

My evinrude 55 only has one 3/8s hole on each side and I just mounted a jack plate to my boat and then realized this ! Is this safe enough to mount motor to plate ? Do people do it

[@THISOLDOUTBOARD1]

Hey. Thanks for tuning in. I don't know that much about jack plates but I see them used all the time. Maybe you can call the manufacturer and find out. Thanks again.

[@TimsWorkshopTJY]

Interesting how parts on those motors are so interchangeable. Kodi has gone over these swapping parts before. I was thinking the 55 would have been faster anyway before the lower unit discovery. Still will be interesting what top end will be.

[@THISOLDOUTBOARD1]

Hey. I think so too. Thanks again !

[@unsaltedlife5998]

I’m looking for a trim until too so what year did they change the trim to the inside one? I have a 1987 40 evinrude

[@ct1762]

1989. you can't convert the 1972-1988 ones to integral im afraid

[@THISOLDOUTBOARD1]

Yeah What he said. Hahaha. Mines an 87 also. Keep an eye on craigslist, offerup and ebay. Sometimes an old parts motor will come up. Check with Kodibass, he might have one. Or get the CMC tilt and trim unit, the one for larger motors, then you can put any motor on it you want. But they aren't cheap. You can find a used one sometimes 300 - $500. Or a powerhead swap with a dead 90's motor with T & T. Thanks again !

@@ct1762 it’s a great outboard so I think I will go with a CMC trim it will also move the outboard back on the pontoon so it sticks out a little more than the toons for better performance.

That is the original gear case on that motor they were bigger and back in the day

[@THISOLDOUTBOARD1]

Hey. Thanks for watching and commenting. I was told by an OMC guy that its not. And I checked the schematic a long time ago and both motors, 87 40 & 79 55 show the same part number. So I'm really confused! Hahaha No just kidding, it does show the same, same props too. I've been doing some homework trying to track it down. It only has 3 water inlet holes and no anode. I've found a few, but it starts to get a little mind boggling! I'll figure it out. Thanks again & Stay tuned !

[@user-bn3zo3mh5v]

I can't wait to see how much difference it makes. Still holding out on putting my 55 carbs on my 40, and I have some Chris Carson racing reeds I can install too if needed. I hope it helps out on torque mostly so I can drive my higher pitch prop a bit faster. Would love to run from maybe 26mph, on up to a solid 30 or 32. Keep in mind I will still be using the 40 block and gearcase so it's smaller. I would have had mine done by now if it were not for 12 hr shifts,piss pouring rain on my days off,

[@ct1762]

no. will actually go slower! you cannot add more fuel and just hope it goes faster without changing the heads (stock .565'' depth, milling it to 45ss spec .515'' will bring compression up to burn the extra fuel). anything beyond that and you need to open the exhaust. so remove air box, up jets to no 56, carson reeds and shave the head while bumping timing to 21 degrees give or take will give you a boost up top, and wont loose much bottom end.

@@THISOLDOUTBOARD1 I have to make a test run the way it is now again because I changed back to 17 pitch prop from the 15 pitchI have been running. Gonna see what happens and see if it's worthwhile since I already have the stuff. We shall see.

[@ct1762]

@@user-bn3zo3mh5v the difference between a 50hp and a 40hp of that era are (for the 50hp) tighter heads, 52-56d jets up from around 38d, reeds with stops, timing to 19-21 degrees depending on year. adding larger carbs will simply make it run rich, and slower without it being allowed to burn extra fuel. give it a shot, but be sure to check the plugs as they will be wet and get fouled really quickly, and carbon will build up on the piston crowns rapidly increasing the chance of detonation over time.

[@user-bn3zo3mh5v]

@@ct1762 I was able to get into the 55hp carbs and the Chris Carson reeds for about 125 bucks so figured I would give it a try. I can switch back quickly if need be. I know I have my timing too far advanced, so I don't run true full throttle. This is a Johnson 40hp 1993 model BTW. I have access to an 80hp Johnson about a 67 model but have been hesitant to do the swap. I don't know how much that would help me, not that I need help. Just one of those things a man likes to tinker with a bit.

[@gillgetter3004]

I think it will be a little faster. Like the heavier duty gear case. Your prayers to the outboard gods must be working👍
