    Mercruiser 3.0 Power Steering Add On

    I found everything I needed for hydraulic system on ebay and spent under $500. I did install it myself (upper and lower helm stations) But I understand not wanting to get into it. I didn't buy this boat so I could spend a lot on it, but that's how it turned out. This should be in everyone's sig...

    Mercruiser 3.0 Power Steering Add On

    @jimn, a hydraulic helm will give you everything you want. Once you get it installed and bled, it is very positive and has no slop.

    Mercruiser 3.0 Power Steering Add On

    Go hydraulic. You can often find used helms and pistons for cheap on eBay.

    2003 Mercruiser 4.3L Trim Pump Leak

    These OilDyne pumps can be rebuilt. There are also some things to do whilst the unit is out. The bottom plastic reservoir is held on by a single long machine screw. There's an o-ring on it to seal the thing from leaking. Also inside the reservoir is a pick up and return that has a filter screen...

    Ran fine last fall, now overheating. Need ideas

    This is like one of those Facebook posts where they ask to solve a math problem with lots of symbols for addition and multiplication but no correct structure so that the answers are all over the place. We need more from you. What exhausts are on there for one. What year were they made? You have...

    water in cylinders and oil - MerCruiser 5.0 MPI -- Need help finding culprit

    Good to hear! Fingers crossed, it'll go for many more seasons! I'd be watching that thing very carefully and checking the oil like every time I shut it off. Trust blown for sure. It isn't out of the question to change the oil again in a month or so after you get the new parts on and run it a few...

    water in cylinders and oil - MerCruiser 5.0 MPI -- Need help finding culprit

    Go to walmart and get a couple 5 quart containers of straight SAE 30 oil. Use this to fill and for the subsequent oil changes. I use this as my normal go-to oil as it's a heavy duty oil and is also a little less expensive. Don't use diesel or anything else that will wash the oil out. You really...

    water in cylinders and oil - MerCruiser 5.0 MPI -- Need help finding culprit

    I don't think this was sudden onset. I think the issue got so bad that it hydro locked the engine when the exhaust pressure was lowered (on deceleration of a warm engine) enough for the water ingress to occur. It was probably there for quite some time. But that's the nature of things. You don't...

    water in cylinders and oil - MerCruiser 5.0 MPI -- Need help finding culprit

    Yes, seriously. They are kinda lightweights. It is a fact that these were offered to keep the price down and still be able to offer the attraction of a V8. If you're happy with yours, that's all that matters.

    How bad is it?

    Milky or no you really want to do the 4 oil changes. Better to spend $100 on oil and be sure everything is good than $10,000 on a new engine or boat.

    water in cylinders and oil - MerCruiser 5.0 MPI -- Need help finding culprit

    Here's the thing. You got water in the engine. You have two options. Run it as is and understand that it is probably on borrowed time and may or may not go south on you when you are miles away from dock/land. Or, remove the engine for a major inspection which includes pulling off the main...

    How bad is it?

    The thing that really sucks about this is the water has gotten into everything, wiring especially. You may be able to save the engine, but I wouldn't be surprised if you continue to experience problems for a long long time. Treat it as if the boat sank. You'll need to do several oil changes over...

    Volvo Penta engine swap

    There is no reason why you can't drop in the 5.7. As mentioned, the v6 uses a different gear set. You may be able to "prop" yourself into a fairly comfortable RPM range by going up in pitch. It's been done lots of times. Now, you would certainly be better off if you had the matching drive gears...
