    Need part 0986272 - Impeller Housing but its obsolete. Any suggestions?

    Agreed! I dont think it’s a cone clutch. If I understand correctly, I think the cone clutch has a bit of a hump on gear case, I do not. My exhaust is through prop I ordered a kit off Amazon that should bolt up correctly but just not sure if having that barb on port side will work. As long as...

    Need part 0986272 - Impeller Housing but its obsolete. Any suggestions?

    I damaged the impeller housing on OMC King Cobra Stern Drive. The housing has a small hose barb on starboard side of housing which vents water to the lower part of the outdrive. The only ones I can find have the vent on the port side. Since the impeller acts as a positive displacement pump...

    New Electric Fuel pump failed after one month

    Would like your feedback. I installed a Carter P4594 electric fuel pump, Low Pressure Oil Switch and a relay to run the pump about a month ago. Last week the pump failed. No warning signs, just quit. I applied 12 volts directly to the pump but it is dead. I don't know if it just failed or...

    Electric Fuel Pump placement suggestions

    I am replacing an existing non-marine electric fuel pump on a SBC which was not machined for mechanical pump. The current pump is mounted to a metal cylinder on the front of the engine. I just bought a Carter P4594 Marine pump replacement. I know it must be down stream of the water fuel...

    Engine miss and new rattle developed in exhaust manifold

    No, the distributor is Pertronix, not a retrofit kit. I suspect it was replaced when the crate engine installed. My OMC manual references Prestolite Electronic Ignition. Your comments above are what cause me to think the ignition spark advance is co trolled by the module in the distributor...

    Power Steering Hose leaking at crimp - Part is Obsolete

    While working on and around the 5.7L OMC Engine I have caused a leak in the power steering hydraulic line running from steering ram to the oil cooler. The leak is coming from the the crimp connection on the hydraulic hose (not the threaded connector). Looks like I may have moved the hose too...

    Engine miss and new rattle developed in exhaust manifold

    I think it’s much ado about nothing as I mis measured my balancer. I pulled the back seat out of my boat so I can actually see what I’m doing. I measured the balancer accurately, and verified that the marks on the timing tab are a match for my balancer. So I think I can trust my TDC mark on the...

    Engine miss and new rattle developed in exhaust manifold

    Gotcha. So would the rattle just be the springs vibrating? Is it detrimental to motor to run it while verifying timing? Looks like I’ve got so work to do there but have to get some parts to find TDC. Is the damper plate between flywheel and the engine? See pic from my OMC manual. I don’t see...

    Engine miss and new rattle developed in exhaust manifold

    Not quite. Here is mine. There is no magnetic wheel. Just the white plastic which what appears to be embedded with magnet or some sort of wheel. You can see the “teeth” through the plastic. i don’t know is the linked procedure is valid for my electronic Module. Pertronix is on west coast so...
