    2.3L shift problem

    Hello. I'm trying to help my uncle get his '90 sunbird back on the water. He is great with engines, but an amateur with stern drives. He's had it for 2 or 3 seasons, and it had been dependable, but it sat for a yr or so, and when he got it back out it had shift problems. It goes in and out of...

    4.3 gimbal service: parts, methods etc

    Found a tear in my u-joint bellows so will be replacing that and the bearing. What about the seal 911795? Should that be done preventatively as well? What's the best way to get it out? Seems like a regular puller would just tear it up -- maybe not? Do I need a special driver to install it...

    Minor (?) Idle issue '89 4.3.

    Hello, We have a new carburetor on our '89 4.3L. It starts and runs well (even after sitting for 2 years doing a floor replacement project). The problem is when the engine is warm the idle is quite high. Our tach has a glitch atm but my guess is 1000 rpm or more. Needless to say, this effects...

    Help with floor coating

    Hello, My brother and I have spent several weekends repairing the fiberglass floor in our old Sunbird. Actually, the real reason was to replace the fuel tank, but our floor was in pretty bad condition so we tore out about 10' of it, full width, repaired some soft stringers, and replaced the...

    Floor project, and other stuff.

    A few of you saw my cut through the hull thread, so obviously we're well underway on our little project, but since there seems to be a little interest (and a significant lack of knowledge on my part) I thought I'd start from the beginning. My bro and I are hard core water sport enthusiasts. In...

    Number 1 bonehead floor repair mistake

    I probably don't need to explain what happened. What's the best way to repair?

    Just found a crack in the block >10yrs old

    So this off season my brother (co-owner) and I had a miscommunication and failed to get the boat winterized. Result was a popped core plug and cracked manifolds. Replaced the core plug and found a pair of used manifolds and began to investigate further issues. Boat started and ran surprisingly...

    89 4.3L starts, runs fine, stalls

    Hi, First trip out after de-winterizing... I started it a few days ago on muffs and things seemed normal. Had to crank it for several seconds, pump the throttle etc, but basically normal coming out of storage. Took it to the lake, fired immediately. Ran fine across the lake for 5 min or so...

    '89 OMC - Adding Sound - current draw concern

    Hi - We have a pair of tower speakers and an amp capable of 300-400w rms at full output -- of course it is rarely driven at full output. It has a pair of 15A fuses. The concern is I am planning to add a couple subs in the foot well area along with a 2nd amp. Total theoretical power would be...

    '89 OMC's bogging a full throttle

    Hi, the old OMC has come out of the gate a little sluggish this season. After replacing fuel fill and vent hoses, the clogged/corroded check valve on the fuel supply line (deleting it actually), some starter work, and a new thermostat gasket and o-ring we finally got it out and running. It...

    4.3 OMC not cranking (yes, the battery is fine)

    Ran fine all summer. Putting it away last fall I couldn't get it to crank, even while being jump started. Didn't have time to fiddle - assumed it was something simple. Got it out this spring to get it ready again, still won't crank. Installed a known working battery, still won't crank...

    My 100% DIY Tower

    My brother built the original carbon steel version with the help of a friend with a few tools and a welder. It lasted 4 seasons, and was a good learning experience, but the fatigue eventually took its toll on the low quality bends, and weak tubing. The recently installed stainless steel...

    Check valve on fuel tank

    Hello, Discovered a fuel supply problem on the '89 4.3L over the weekend. There was a check valve that connected the engine's fuel supply line to the fuel tank and some debris had built up and was causing the ball to stick. As we were disconnecting things, that valve broke. Temporarily we just...

    Motor got wet - now won't run

    Hey - finally found the time to finish de-winterizing and went to the lake for a check. Started and ran well - as expected. After running for a couple minutes I discovered a pretty steady water leak toward the top of the engine. The thermostat housing wasn't properly torqued which was causing...

    OMC Cobra lwr shift cable/pivot housing probs

    I'm replacing u-joint the bellow and some washers on the pivot hsg. I got the housing off, but getting it free of the lwr shift cable was a real hassle, and I had to put a lot of bending force on the cable as I rotated the housing. I tried to pull the shift cable out for an inch or two more to...
