    1988 Borg Warner 72c leaking

    So I have a 1988 crusader mated to the borg warner velvet drive. It appears to be leaking where the transmission bolts to the reduction gear. The interesting part is when I checked the fluid the next day there was a pressure release when I pulled the dipstick. Is there supposed to be pressure...

    Mercruiser 8.1 smelly exhaust

    My buddy has a cruisers 340 with 8.1 mercruisers. The port engine only turns 3600-3700 rpm but the starboard runs to 4300. The exhaust smells like unburned fuel on port side as well. We see no gas sheen on water however. Any ideas on what the problem could be. We are thinking maybe one cylinder...

    what causes a Rochester quadrajet float to stick?

    The boat was not run for 2 weeks so obviously the gas had evaporated out if the bowl. The crusader 454 has run flawlessly for years. When I went to start it it cranked and cranked. It took 2, 10 second cranks before it started due to lack of fuel. That I understand, but once it filled the bowl...

    1986 454 1 exhaust manifold hot.

    What would cause the starboard manifold to be hotter than the port. The port one I can touch forever but the starboard one is close to too hit to touch. Temp gauge reads 140. I replaced the raw water impeller and raw water belt. No improvement. Removed thermostat no difference. A circulating...

    Dropped my whaler with the above engine in the water yesterday for the first time this spring. I changed nothing over the winter.

    1999 mercruiser 454 fuel injected idle too high

    My friend just bought this boat. A 1999 sea ray 34. The port engine idles at 1200 rpm. Is that a turn of the screwdriver fix or is that a computer problem? It runs great otherwise.

    2006 johnson 150 question

    I bought a used johnson 150 a few years back. Aside from the warm start heat soak issue i love the motor. My question is it has an OIS oiling system which to me looks like the old VRO system. Is that correct? If so, were all the kinks worked out by 2006 or should i consider premixing oil?
