    MAG 350 loses power after 20 minutes, need help

    Your minor changes to the SBC won't get you to 50MPH while only turning 3500 RPM unless it's in a truck pulling the boat on a trailer Based on only turning 4000 RPM at WOT in past, you're lugging the motor. Lugging a motor kills them. Prop the boat so the motor turns 4800-5100 RPM at WOT...

    Mercruiser 5.0 crankshaft front oil seal replacement

    Yes, auto makers now make plastic intakes, plastic oil pans, valve covers, timing covers. For a vehicle that lasts 4-8 years it's not a problem. However in a boat that lasts 15+, it's a real issue One of the many reasons I prefer to refurb/rebuild vs buy new Luckily the aftermarket SBC...

    5.7 Automotive Intake manifold

    And the block-offs for the back of the head. I have never found an epoxy to hold up and ended up getting a marine manifold. POR15 used to advertise an epoxy, however their product has been crap since 2008. Edelbrock (made by Barr castings) has marine manifolds that are nearly identical to the...

    5.7 Automotive Intake manifold

    Because even in fresh water the manifold will corrode. Not as fast as in salt, however it will still corrode You can run an auto manifold if you have a heat exchanger

    V8-270-C-B Exhaust bellows (hose) replacement

    covered in the factory manual. Since you have CAT's in the exhaust, I would definitely look at the manual. (I dont have a copy) additionally, those hoses should last 30+ years. only failure to maintain cooling water system would kill them (lack of water and exhaust temp goes from 200F to 1200F)
