    Volvo 5.0Gi compression issue - need to replace an intake valve

    My port engine started having an issue with back-firing through the intake when under load near the end of last season with about 750 hours of runtime. I replaced a bunch of stuff before finally doing a compression test and determining that #2 cylinder was pushing zero compression. So, I got...

I have a sensor with a spade terminal and a single wire mounted in the oil filter housing on the port side of the engine and another sensor on the top side near the distributor with a single screw terminal.

    1999 5.0Gi Exhaust Manifolds and Risers replaced (x4)

    I just replaced exhaust manifolds and risers with Volvo Penta OEM risers and Barr manifolds. Damn those manifolds are heavy! I had four of them to do.

    2000 5.0GI PEFS Fuel Pump O-rings

    I'm having a fuel pump issue on one of my engines, and rather than spend $700 to buy the entire Fuel Cell, I took everything apart to clean it out. Now, I need the two O-rings for the bottom of the vapor separator. Of course, these O-rings aren't available at the VolvoPentaStore Anyone know...

    I see two part numbers that look like the correct pump, but not sure which is the one I need for my 2000 5.0GI PEFS engine. The part numbers I've seen are as follows: 21214595 21214599 My pump uses a serpentine belt and the pulley mounts directly to the harmonic balancer.

    Volvo 5.0 SX only 4000 rpm at WOT

    I have a Cruisers 2870 with dual 5.0 Volvo SX DuoProps. I just bought it a couple of weeks ago. The starboard engine will only reach 4000 RPM at WOT while the port engine will hit around 4700-4800. Possibly a throttle cable adjustment of some sort? Any help would be appreciated.

    Cruisers Yachts - 2870 Express - Review

    I'm considering a purchase of a 2001 Cruisers Yachts 2870 and would like any feedback that any of you may have on Cruisers Yachts in general, and specifics, if you have any. The boat has dual 5.0L Volvo engines - not sure what outdrives. Seems to be in really nice shape according to the...

    Marine parts vs stock Chevy 350 parts

    What parts on a Mercruiser 350 are marine specific? Can I replace the recirc pump with a stock 350 Chevy water pump? How about intake manifold, etc? I know the starter and alternator have to be marine specific since they are electrical and running in a potentially corrosive environment. What...

    Mercruiser riser gaskets - Restricted vs. Open

    I went to buy some riser gaskets today for my Mercruiser 350 (1989 model) Alpha One. The parts guy gave me a "Restricted" gasket, and after pulling the port riser, I see that the gasket that is currently on there is the same type. Can I use an "Open" gasket to increase water flow, or should I...

    Mercruiser 350/260hp - run without thermostat?

    I have a 1989 Sea Ray with a 350/260hp Mercruiser w/ Alpha One outdrive. Is there any reason that I shouldn't run it without a thermostat? I'm having overtemp problems at idle - especially after running down the lake on plane for a few minutes, then dropping to an idle - temp quickly climbs to...

    Mercruiser 350 engine oil change

    What's the best way you all have found to drain the engine oil from a Mercruiser engine? I don't have a drain tube on the oil pan. I have been looking for a pump that I can use through the dip-stick tube, but every one I find, there are horrible reviews saying that it doesn't work well, etc...

    Hi all. Long time no see :) I have a 1989 Mercruiser 350 with an Alpha One outdrive and I'm having a problem. Problem indications: When using a stainless steel prop, the boat will not plane. It gets about halfway to plane at about 3500 RPM, then the engine revs and the boat loses all power...

    Mercruiser Alpha One dies when shifting to reverse

    Hi all, My Mercruiser is a 1989 350 Chevy power pack with an Alpha One outdrive. When I shift from neutral to reverse, it dies - almost every time. It goes into forward gear just fine, every time. It tries to die (and sometimes succeeds) shifting into neutral from either direction. I found a...

    Mercruiser comes out of gear while underway

    Hi All, I have a 1989 Sea Ray 220 with a 5.7L Mercruiser and Alpha 1 outdrive. It has worked wonderfully for me for the last two years. This past weekend, I took the boat out and it worked fine all day, up until the very end of the day. I was cruising along at about 20-22 mph, on plane...
