    Pulling outdrive question????!!!

    well you will hear different stories on that. I know in my OMC manual (for the pure OMC model) they did say to use OMC Gasket sealer on the flange of the gimble housing. So that's what I did. But some have said that Volvo says no sealer necessary. I coat the part of the bearing carrier that...

    Pulling outdrive question????!!!

    joint venture is what you have other way you could tell is if the raw water impeller is mounted on the engine, if it is then its a joint venture drive. The pure OMC Cobras had the impeller in the tail end of the upper gear housing, both the dog clutch ones the rare cone clutch one. no gasket...

    2004 volvo penta 5.0 gl-e camshaft

    that's a lot of pitting, did the engine sit with water in the oil at some point? I had 2 blown head gaskets, water in the oil (salt water) and was able to get the water out of it within a week changing oil 3-4 times. When I did the top end overhaul, I pulled out all the roller lifters to...

    Pulling outdrive question????!!!

    Yep just think of the joint venture drives (hump on top of upper gear housing, not flat like a pure OMC Cobra) as the same as a Volvo SX. The similarities are really just in the transom mount, the drives themselves are totally different.

    True for old boats the I/O still makes sense even more so if you grew up around Chevrolet small blocks and know how to rebuild carbs, set timing, etc. Then, they were simpler than a carbed outboard that had a carb for each cylinder (so a V6 outboard had 6 carbs to worry about).

    Missing seal / gasket??

    No gasket needed its just like a volvo penta sx. You shouldn't add one either, Just coat the part of the bearing carrier that presses into the bellows and the lip of the bellows that mates up with it. In fact I'd coat the surface of the upper gear housing that mates to the pivot housing with...

    Glue vs clip VP SX exhaust bellows

    pulling a VP SX is very similar to pulling any other, you need to know if it should be in neutral or in gear and I recommend the use of a drive jack and an alignment tool. I would just install the exhaust bellows with the snap ring instead of what was suggested. If you're going to own this boat...

    350 mag, gauges dead, all other electronics seem fine.

    Check the ignition fuse; if ok then move on to the ignition switch. B terminal (red wire) should have battery voltage any time your battery switch is on and when you turn the switch to ignition on the I terminal (purple wire) should have battery voltage. If this checks out then go back and check...

    Replacing Trim sender with after market

    Well I can't say for sure on a V/P drive but on my OMC Cobra drive I replace the OE trim sending unit (because the originals were NLA) with a Sierra one in 2010 and it still works! The OE ones never lasted that long.

    Missing seal / gasket??

    This depends on which drive you have. A 1986-1993 OMC Cobra should have a gasket there, whereas the 1994 and up joint venture with Volvo Cobras do not, just the same as a Volvo SX. So if you have up to and including a '93, yes there should be a gasket, but if its a 94 and up no gasket. Looks...

    really think this thru though... cat converter exhaust, if you are in brackish or salt water... Merc V engines, 4500 in parts Volvo V engines 6000 in parts then there's: more difficult to winterize difficult access for some repairs, do you realize what a horror show some I/O installations make...

    That sounds wrong but maybe the Vortecs can tolerate more advance than the pre Vortec due to the difference in the shape of the combustion chamber.

    VIDEO Help: Post Texas Freeze Leak

    By the vid it could be just the manifold or the engine as well but seeing as how both were full of raw water it sounds like you will need a new or reman long block + exhaust system and anything else that could have froze...power steering cooler, raw water pump, plastic water nipple in the pivot...

    1986 Galaxy OMC Outdrive Gears

    Here's a (salt water used) Cobra...what does yours look like? As noted a 1986 boat could have either because some came with 1985 drivetrains some came with 1986s.

    I think for that price you can do better. If its an I/O and it has cat converter exhaust stay away from it. Exhaust replacements on those will break the bank. I'd never buy one for myself. Get a late model boat decent quality with a modern 4 stroke outboard. Look at Key West Dual Console models...

    Hope you get it up & going well after all the time you spent on the conversion last year. Looking back in my OMC shop manual for some reason the 4.3 was set up with a good bit less spark advance than the V8s. Not sure if this is peculiar to the pre Vortec engines with full dished pistons or...

    Mercruiser exhaust systems.

    Yes great explanation Chris and definitely one of Mercury’s better ideas. In fact when I did my top end overhaul 4 years ago I considered changing to the Merc dry joint. I had the OMC one piece units (NLA years back) and I knew the newer 2 piece style used by OMC & Volvo would fit. The angles of...

    4.3 Mercruiser cold start issues

    The Quadrajet is an excellent carb if you can start with an unmodified core. Even though they have not been made in 30 years you can still get most parts
