    Possible boat purchase!

    The Volvo SX is a development of the OMC Cobra where during the joint venture between OMC and Volvo the Cobra drive was re-designed from dog clutch shifting to cone clutch shifting and identical models were sold from '94 to '98 under both brand names, after '98 Volvo bought out the rest of OMC's...

    Impeller challenged...?

    That way of installing the impeller is not really necessary, because you can use a sticky marine grease like Evinrude triple guard to hold the o ring in the impeller housing slot and it will not move out of place when you have to twist the housing to get the impeller on. I like to lube up the...

    1986 Mercruiser V-8 5.7L - overheating issue??

    Those holes are blind on GM cast iron intakes. What I’d do is put the boat in the water and bring a 5 gallon bucket. Look up Mercs test for the volume of water that impeller should pump in a set amount of time. That will tell you if the impeller is supplying enough water. However for a complete...

    Won't shift into gears. somethings seems stuck.

    Yes that is correct. What happens is that the notches or 'dogs' in the fwd and rev gears are cut in such a way that they stay engaged under power, since those small gears have to transfer all the power of the engine to the prop. So when you want it to disengage, its going to resist that and...

    Won't shift into gears. somethings seems stuck.

    No it does not shift gears like a car just Fwd Neutral and Reverse

    Won't shift into gears. somethings seems stuck.

    That will cause starting problems but not usually running problems. I’d go thru everything on this boat esp bellows, cable, ESA function and battery cables. Stock boat battery cables are usually crap. Remember the ESA lowers engine idle when shifting from in gear (Fwd & rev) to neutral, not...

    Won't shift into gears. somethings seems stuck.

    The bubbles like that are not normal, your exhaust bellows (lower bellows) is installed upside down, the slits should face down. The way it is, its exhausting hot water right against the shift cable and the upper (driveshaft) bellows. There is a normal clunk when shifting into gear, common to...

    2000 3.0 L engine temp fluctuating

    Test the stat, does it open at the right temp? If not just replace it.

    Thru hull exhaust

    Metal pipes can be made up by a muffler shop but you have to use proper marine High Temp hose to make the connections.

    Thru hull exhaust

    It looks like the boat did come with a small block judging by how the outlets in the transom are set up. I think you’d need to get the pipes made custom to mate up with the thru hull exhaust.

    4.3 GXi-J with DPS-A howling sound

    My 4.3 4bbl Cobra sounds similar but the Cobra drive itself is very quiet. However with the extra strength of square cut gears I wouldn’t mind a little noise

    Need second battery pointers

    On small boats the “house” and engine loads are not wired separate so the easiest thing to do is to use the simple 1,2, 1+2 and off switch. Just alternate use of each battery and never leave it on “both” since one bad battery can kill the good one. The only time you would use both is if both...

    4.3 GXi-J with DPS-A howling sound

    I looked at some pictures of the gears used in the SXA series and they are indeed square cut gears not like the more typical gears used in the SX series. Like a heavy duty racing transmission they may be inherently noisier. As long as there are no unusual wear particles I don’t think I’d be...

    4.3 GXi-J with DPS-A howling sound

    Bluish sounds like they may have used the Mercury High Performance gear lube which may not be the best choice for the Volvo although I don’t know what color the OE Volvo gear oil is. I have heard reports on some forums that the later model Volvos used straight cut gears which naturally make...

    should I use a support for my outdrive on my H190?

    They make plastic clips that fit over the trim piston rods for this. If you can store the boat with the drive down because the driveshaft bellows will last longer that way.

    Volvo Penta 3.0 I/O Overheating. Brand New Engine!

    I'm sure you'll get it sooner or later. Definitely don't give up. These I/O cooling systems can be tricky. So you are fixing the old boat too? I hope so, I love the classic lines of the old FWs. Couple of little things....on the Volvo SX (just like the OMC Cobra) there is a plastic fitting in...

    Water in oil, could this be the issue?

    Before you install them check the mating surfaces with a straight edge and feeler gauges, mine were flat to less than .001" If you are in salt water I'd put a better coat of paint on them because the OE paint is thin. I just brushed on a couple of coats of rustoleum. The manifolds don't or...

    Water in oil, could this be the issue?

    I installed a set of Barr manifolds 4 seasons ago and they fit perfect with no leaks.

    1992 Mercruiser 4.3 w/ balance shaft and 1 piece rear main seal swap to newer year Vortec.

    When I did my top end overhaul I used reman pre-vortec heads, I'm pretty sure they were just automotive heads, no different, about $550 for the pair.

    Impeller housing overheating

    And ignition vs carb as a cause of bad running well both can be implicated but ignition is both easier to troubleshoot and to fix. You can easily see fouled spark plugs burned points , or a corroded distributor cap. A carb well you have to do a lot of disassembly to see what’s up with it and...
