    1986/87 Crusader 270 Stalls about 5 minutes AFTER running fine

    1986/87 Crusader 270 (I say '86/'87 because I seem to have two engines that have some 86 parts, some 87, but are both original.. perhaps right at the change from 86 to 87 productions.. IDK) Engine starts, idles, runs great. Go out on water and run both engines up to crusing 3200 RPR, runs...

    Crusader 270 Misfire/Rough Idle

    I have 1987 Carver Mariner 3297 twin Crusader 270. Port side was sounding and feeling a little off, then blew head gasket (in 5-6' swells in the middle of Lake Erie of course!). Pulled heads, had heads re-done, cleaned out block, reinstalled everything, new plugs, wires, points, cond. cap &...

    Water in Oil, under valve covers only (maybe)

    1987 Crusader 270 GM 5.7l 350ci. While cruising in Lake Erie yesterday, lost power on port engine (syncronizer pegged to starboard).. She would not hold RPM above 2800, but held anywhere up to 2800. Throttling up past that she would bog down. My first though was a clogged fuel filter based on...

    RH & LH Timing Help Needed

    OK, I got 1987 Carver with twin Crusader 270's (5.7l GM) with V-Drives. So if I'm standing on swim platform, looking towards the bow, facing me is the belt/balancer end of the engine, the transmission side is forward. (basically, my engines install in reversed position). So my STB side engine...

    Crusader 270 Service Manual? Anywhere?

    So I got a different boat a few years ago that has 1987 Crusader 270's. I thought I would have better luck than with the OMC Cobra I/O's that I had on my previous boat, as I assumed Crusaders where fairly popular. I have since come to find that it seems to be difficult to get any info about...

    Should I Change BW V-Drive Trans Fluid??

    1987 32' Carver Mariner 3297. Twin Crusader 270's with Borg-Warner V-Drives. I (had) replaced starboard side trans and v-drive 2 years ago when I bought the boat. No other history on this boat as it has changed hands several times by the time I got it. Engine hour meters are at 680. The trans...

    Water Heater Exchanger Leak?

    I'm in the process of troubleshooting a fresh water problem. The indicator is that the fresh water pump will not shut off once all tap sources are closed. I have already cleaned the strainer, checked all fittings from water tanks to pump, and visually inspected all visible water lines for...

    Fresh water, pump pressure troubleshooting

    I just acquired a 1987 Carver Mariner.. very nice boat. Only problem is there is almost no water pressure at any faucet. The water tanks appear to be holding pressure without leaks, but the water pump will never shut off either. Its a sureflo pump, about 17 years old, 2.9gpm with a 45PSI...

    Can an OMC Outdirve Run In Reverse (as Forward)

    OK, I almost hate to even post this question because I just dont this it's possible.. but here it goes. I have twin OMC Cobra 5.7 on a Four Winns 285 Vista, 1989. Two seasons ago, I needed to replace my port side outdrive. I could not find a CR outdrive, so I replaced it with a standard...

    Port Engines makes "shuttering" noise

    OK, I almost didnt post this but just looking for support of my theory. Two seasons ago, I boat a new-used outdrive (OMC Cobra 5.7, 1989). I could not get it installed, alignment seemed off. I had a local marine shop install it. I had a short season that year due to other issues. Last...

    OK to replace LH Cobra outdrive with RH ?

    I have 1989 Four Winns 285 Vista. Twin 5.7l OMC Cobra Counter-Rotating drives. My mechanic told me that the forward gear on my port-side (LH) outdrive is blown out. This is the counter-rotating side, and apparently these LH-gear sets are like gold (hard to find). If the mechanic can find the...

    OMC 5.7/350 50amp Fuse lead to ?

    I'm reinstalling my port side engine, after a complete transom/stringer rebuild. The fiberglass shop removed/reinstalled the starboard side, but did not connect the 50amp Fuse leads (soming off the solenoid). I'm not a mechanic, so I was using the starboard side as my reference. The only...

    OMC Cobra 350's 50amp connector to what?

    I'm in the process of reconnecting all of the wiring harnesses (engines pulled to rebuild trans/stringers). I have OMC 350/5.7 Cobra's. There are two 50amp fuses that mount near the harness on top of the engine. Each of them have a wire coming off of them with an eye-connector. I assume these...

    Remounting Engine after Stringer Rebuild

    I have an 89 Four Winns 285 Vista. I just had the stringers and transom rebuild. They shop reinstalled the starboard engine, but I had already pulled the port side before I took it in for the repair. They did not install the engine mounts for the port engine, and said I need to put them on...

    I have an '89 Four Winns 285 Vista, twin 5.7 Cobras. Last season, I noticed some dirty water marks in he bildge near the outside port stringer (causing streaking under the engine).. I just starting working on her this Spring, and I crawled in to check things out. I noticed some "spidering"...

    Transom Seal / Water in Bildge

    I have a 1989 Four Winns 285 Vista. She has always maintained about 4" of water in the bildge since I had it (about 5 years). In the past, I asked the local mechanic about it, and he said it wasnt a big deal. Lately, it seems that there is a little more than usual. I was considering changing...

    89 OMC Cobra 350/5.7 29'Four Winns I replaced a gimbal bearing on stbd. side. After installing the new bearing, my alignment tool does not go through to the coupler. As I try to push it in, there is pressure pushing it doownward. I think I have the bearing in straight, and as far as it goes...
