    Help - low $ solution suggestions - Mercruiser 5.0

    I've been working on my boat off and on for over a year and the wife is getting antsy. I had to rebuild the heads on my Mercruiser 5.0 as the exhaust elbows leaked and locked up a couple of valves. I was going to reinstall the cast iron intake but it's pretty corroded as the boat is in...

    96 Polaris SLT 780 stalled, won't turn over

    I have a pair of these and we were running them today. While at near-full throttle, it stalled. I got it to start, but it wouldn't run full open. I nursed it back to the beach and checked what I could. Apart from a corroded battery cable, everything looked fine, but it wouldn't turn over. We...

    90 hp Johnson won't start - advice?

    My pastor has solicited my help with his 90hp Johnson motor. It did run about a year ago, but after sitting idle for too long, it won't start. I'm used to working on inboards so I'm not familiar with this engine. I've checked spark, it's there, but not as bright or hot as I'm used to seeing on...

    Rebuild 5.0L heads

    I'm going to have the heads on the boat rebuilt. Since it's the GM engine, can I take them to a regular shop to have them rebuilt or do they have to be done by a marine shop? Thanks!

    Alpha 5.0L - Replace manifolds with risers?

    The port riser on my Mercruiser 5.0L started leaking and I've pulled things apart. I don't see any obvious problems with the manifolds. Do I need to replace the manifolds with the risers? Not a lot of income lately so I'm trying to watch my pennies. Thanks, Greg

    Bent Valve - 1994 5.0L Mercruiser Alpha

    Bent a valve - heard it knock 3 or 4 times while running, took the valve cover off and found broken pushrod. I'm going to pull both heads tomorrow and take them to get them rebuilt at the local machine shop. I've built several car engines so the work doesn't intimidate me. Is there anything I...

    Alpha One trim hoses

    The crimps on my trim hoses finally corroded away. Funds are a bit tight (surprise) so I'm wondering if there are other options, i.e. braided auto brake lines? Also, if I plug the hydraulic ports on the bottom of the stern drive, can I still run the boat for a few days without trim? My boat...

    Alpha 1 - 5.0L - Idles fine, runs WOT fine for a short time then stalls.

    My alpha 1 - 5.0L idles all day without issue, but when I take it out to really run it, she runs great for 10 or 15 seconds then tries to stall. If I bring it back to idle quickly enough it idles great. My first thought is fuel filter or water sep filter. Before I drop it back in the water -...

    Alpha 1 tilt/trim won't go down.

    I just acquired a boat with the 5.0 Alpha one series drive. The problem is that the drive will go up without a problem, but it won't go down without someone standing on the drive while the tilt/trim switch is pushed to the down position. The pump is trying at least to make it happen, but...
