    What type sterndrive

    Gear lube or engine oil? Have you carefully checked OD? If not leaking lube, it has to be engine. How much is much? Is it worth all the work for a missing quart a season???

    Trim cylinder hose replacement

    Most systems will automatically purge. Seal kits are cheap and offer peace of mind. Easy to install... Easy to flush. I would have open rams and flushed and then add new fluid. Pump our reservoir. Check manifold connection at OD. It has a gasket that sometimes leaks. Cheap to replace.

    engine oil

    U live in south or north??? In NW Florida many burn 10w30/40. Crank up with 10w30 and see if it burns excessive oil. U may have to thicken oil. Most motors don't wear out, they corrode or rust out.

I had to purchase a cheap automotive 12 volt pump and cycle fuel sever times, after removing pickup tubes' screen, to clean tank. Pulling tank...

    Not getting water to crank pumps-Bravo1

    I will examine cover. I believe I have it correct. Output water/hose from transom Bravo-itus kit comes from port side of each engine to crank pump.

    MC Chevy V8 Bravo 1 Crankshaft water pickup pump issues

    Boat sat in my driveway for about 4 years due to health issues. When I put it up 4 years ago it ran very well. Both motors were about the 150-degree temperature range during sea trial. I am very familiar with Alphas, but it looks like former owner may have skimped on the best water pick up...
