    Volvo penta sx making noise

    I have a '94 four Winns with twin 302 / SX-M outdrives. Last year I noticed a whining noise from the Port engine. It was very noticeable while cruising at low/idle speed. I removed the drive and found water inside the bellow. The gimbal bearing was rusty and replaced. I also noticed water...

    Volvo Penta 5.0 running rich - loss of RPM's

    1994 Four Winns Vista 278 with two 5.0 Ford carbureted motors. My port engine seems to smoke a lot at times with a thick, black smoke. It reeks of gasoline when idling and for a while after shutting down. I recently rebuilt the carb (2bbl Holley). Since replacing the carb it still smokes and...

    I have a Sport Jet 90 with a CDI switchbox (114-4953). Can anyone tell me which is the black/white wire that comes from the switchbox. The black stripe has rubbed off of one of the wires.

    94 278 Vista Cruiser - can someone decipher the dual battery system

    I have read the manual on this, searched the forum and still don't know how this works. I have twin 302 fords in the boat, thus dual batteries and dual alternators. I don't understand what is being charged and by what. I run the boat with the battery selector switch in the "on" position...

    Sportjet 90 - Is this more than dirty carbs?

    Sportjet 90 - just replaced stator, good spark. Took it to the lake and started up just fine. I was just about ready to turn the boy loose in it and it abruptly died. It wouldn't start, although I still had spark. I was able to get it running by spraying pre-mix gasoline into the carbs and...

    Sportjet 90 stator - need quick answer

    95 Sportjet 90. Last year I upgraded to all CDI ignition and the boat ran, finally, for the whole last day we used it. I did nothing to it other than winterize. Prior to first outing all I did was charge the battery. When I tried to start, absolutely no spark to any cylinders. I cleaned all...

    Help please! Is this part available? Gimbal plate water fitting

    Help, I have 94 VP SX-M in Four Winns cruiser. I removed the gimbal plate (I think this is what it's called) to change the bellows, bearing, etc. On the plate is a plastic fitting that the S hose is connected to. It then feeds through the gimbal plate and a large plastic nut secures it in...

    Sport Jet 90 Regulator question?

    Okay, I'll try this again. I have gotten little to no help here and don't know why. I know there is help out there. There is 12.7 volts reading between the case of my regulator (both old and new one) and the engine ground. Surely, this can't be right....Can it? With the regulator removed...

    1994 278 Vista Porpoising

    I have a '94 278 with two OMC / Volvo 5.0 and OMC SX / VP drives. I haven't had it very long. When I get on plane it is almost uncontrollable with porpoising. I have the drives all the way down as the boat is in a slip and I leave them that way all of the time. My trim tabs rarely work, but...

    I am replacing a blown head gasket. There are four (maybe more) black plastic tubes wedged in the water jacket around the cylinders. Can anyone tell me what they are for or if it is necessary to replace them?

    Can Sport Jet 120 replace a sport jet 90?

    I have a line on a complete, running Sport Jet 120 to replace my Sport Jet 90 in a 95 Baja Blast. Will they interchange? Are the pumps different? I am guessing the 120 is considerably taller since it has one more cylinder.

    Is Force Sport Jet powerhead the same as Mercury?

    There is a seller on Ebay listing Rebuilt Chrysler / Force 90 HP Powerheads (either L-drive or sport jet). My understanding is that the Force sport jet 90 and Mercury sport jet 90 are exactly the same thing. I called the guy and he wasn't sure. Is there any difference at all? Is there...

    Sport Jet compression issues

    I have a 95 Sport Jet 90 with WOT power problems. I originally thought it was a bad fuel pump. I checked the compression today and found 100 PSI on #1 and #3, but around 50PSI on #2. I am assuming this is a burned piston since the only way I could start cold was with staring fluid (wished I...

    Mercury Sport Jet 90 bogs down at WOT

    I have a '94 Baja Blast with SJ 90. It has never started without first having to "prime" it with starting fluid. Once warm, it ran great and started immediately unless it had sat for a while, then more starting fluid. I recently had to replace the rev limiter (previous post). This past...

    Volvo Penta (OMC Ford) smokes

    I have noticed that my starboard VP/OMC 5.0 seems to smoke and produce more fumes than the port engine both at idle and while cruising. You can actually smell the fumes while in motion. I just rebuilt the carb on the engine and it runs very well. One thing that I have failed to address is...

    Mercury Sport Jet 90 - No Spark

    I have a 94 Baja Blast with SJ 90. Jut got it and took it out last week. Took forever, and a blast of starting fluid to get it started. Once started, it ran great. After a while of tubing it just died and would not restart. Today I checked spark. Nothing on all three cylinders. I...

    1994 OMC 5.0 Water Intake / Cooling Problem

    I have been having cooling problems on my starboard 5.0 (ford) OMC on a 1994 Four Winns 278 with OMC / VP SX drives. I ruled out impeller, gauges, sending unit, thermo, etc. as cause of problem or reason for false readings. Today I hooked up a clear hose from raw water pump to thermo housing...
