    Sea Ray 1977 200SR

    Try looking on Barr Marines website to see if they make a version of that manifold. If you REALLY love that boat and want to keep it fix what’s needed to get it going but if it’s a constant headache think about doing a transom rebuild and swap in a modern (Mercruiser) drivetrain. Big job but...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    If you do it your self there’s 2 things to get past: 1) end caps, these can be tough to get off, I used heat time & patience 2) removing the eyelet end that’s on the piston rod, this has to be done to replace 2 of the seals in the cap. Micheal Romer covers both in his vid I advise leaving the...

    Looked at it, might be the same thing with a different part #. There are basically 3 seals for the end cap and 1 oring and 2 split rings for the piston.

    Did this engine have those one piece batwing manifolds on them? I know you said the passed the acetone test but I wonder if they leaked when they got hot? Those manifolds were known to be troublesome, I think they were used from 96-99. There is a Merc conversion kit to change it to the normal 2...

    OMC original parts are readily availably here in the USA try marine engine.com, not sure if they ship to UK. A good hydraulic shop could do it but as long as you can get those end caps loose (pin wrench) & you have the right parts you can easily do it.

    That looks like it You have to compare the seals you took off to what’s in the kit because they usually include ones you don’t need

    Bombardier Recreational Products They are the company who bought OMC’s assets after the bankruptcy in 2000 and who still market OMC parts. Check Marineengine.com for parts…the kits have the orings needed for repair

    Forgot to mention, what the pictograms on the drive are trying to communicate is do not remove the fill plug with the drive down or else you can get a shower in hydraulic fluid! tilt it up first. That's what I did after rebuilding my cyls and bleeding the system (5 up and 5 down cycles).

    Yep I see the difference. You'll wind up with a much better built boat than you can buy!

    very old pix from 2007 when we did this....not the greatest job but still solid... I used mahogany for the gas tank mounts, it is really rot resistant.

    About the anodes, they are a little different on this one vs the dog clutch Cobra, just alike a Volvo, there is one under the transom mount, one on the front end of the drive and one inside the bearing carrier. The dog clutch models had that small cube anode like the Johnson and Evinrude...

    Hard to say why it’s bleeding down it could be either the cyls or the pump. If you rebuild the cyls & it still does it then it’s the pump seals. I rebuilt mine because one side was leaking and both of the alu end pieces that the rod goes thru were really corroded. Had to fix it. What I did was...

    Well here’s the thing The selection of the prop has to do with the gear ratio of the outdrive which is basically linked to the engine size. Bigger engines can use taller gears smaller ones have to use shorter gears. Now what you want is for the engine to reach the max rpm specified by the...

    Oil coolers I agree would have been a good idea, they have been used in high performance big block applications, but not on less expensive more consumer grade boats like ours. This is exactly why I advise no car based oil in a marine inboard, with no oil cooler. It will shear down the oil and...

    Well the flat tappet cam issues it's more an issue with break in on a new engine or a high performance engine. With a normal performance engine, already broken in, I don't think it's a big deal. The straight 30 recommendation is from years ago. You can use that, straight 40, or 20/50, or Merc's...
