    1996 Horizon 220 5.0Fi raw water pump issues.

    If you have the dual inlet muffs with the hard rubber rectangular muffs they might not allow the pump to prime. I had trouble with those and switched to the Merc/Quicksilver round ones made out of much softer rubber. They fit better and the impeller primes easily. With the Volvo impeller way up...

    In addition to all the other good suggestions the anti siphon valve if corroded or partly obstructed it will cause fuel starvation and low WOT rpms

    Replacement for perfect seal on drain plugs

    The idea of the sealer is to keep the threads in the block from rusting, mine has the brass fittings screwed into the block and the brass drain plugs screwed into that but I still use sealer. If your plugs go right into the threads in the cast iron block then for sure use gasket sealer, grease...

    How to tell what carb I need?!?

    1) the Quadrajet is an excellent but complex carb, for marine use the small primaries and huge secondaries work very well. 2) these were last made in 1989 or so so they are all very old and you don’t even know if it was a marine or automotive unit (look for the yellow overflow tube between the...

    Replacement for perfect seal on drain plugs

    You can find Evinrude gasket sealer on Amazon I think it’s the same product as the Merc perfect seal. I have also used Permatex Aviation and not had trouble getting them out. Are you using metal plugs or the plastic Merc ones? Another option if using metal plugs is just trailer wheel bearing grease

    Volvo penta xdp outdrive removal.

    PS the driveshaft bellows probably leaked water sat in the bellows and corroded the driveshaft splines into the coupler.

    Volvo penta xdp outdrive removal.

    BTW Yes this is a bad product by VP, in their “gererosity” they offered an upgrade program where you could buy an SXA drive and transom mount for a discounted price of something like 9 grand or some such... And: You own ANY outdrive boat and don’t pull the drive at the end of the season to check...

    VIDEO Help: Post Texas Freeze Leak

    If nothing was drained everything is cracked, manifolds, block, cyl heads, intake manifold. Sorry but these engines were originally designed to be in a Chevrolet with antifreeze and a pressurized cooling system. The fact that Volvo and Merc thought that they could save money and keep prices of...

    Hydrolock, swim platform, riser height and static water line question

    OMG you could have done better yourself with a large enough belt sander

    Glue vs clip VP SX exhaust bellows

    and if you get water in the gear oil if enough gets in you will have the drive pressurized and some can leak past the input shaft seal and then you can get gear oil in the bellows!

    VIDEO Help: Post Texas Freeze Leak

    What's the boat worth? What would it cost you to get another boat? If its worth something (assuming you fix it) and you can get a long block + exhaust system replacement, then I would fix it, prices could be between 6000-8000 depending on new vs reman, and your local labor rates. I hope people...

    Pulling outdrive question????!!!

    agreed I'd use their stuff, since the cone clutch in the joint venture products is a Volvo design. I have head of problems with the cone clutches if you use others. Pricey but its a once a year expense. Same was with motor oil etc. I use the Merc 25/40 motor oil because I feel it protects...

    Volvo penta stern drive longevity

    As far as I am concerned with proper maintenance and fixing problems before they become more serious (leaky bellows, leaky seals) outside of strike damage just about any outdrive can last over 30 years. The Cobra I still have has not had any mechanical repairs to the bearings, gears etc since...

    Riser To Manifold Torque w/Sierra gasket

    I did it 4 years ago so I can't remember exactly where I got em but I think it was from the TSB that seems to have disappeared. Those are the specs I used, using the Barr gaskets and no leaks at all, salt water use. But the Volvo updated gaskets are different, so if I was using those, I'd follow...

    Need help with parts list- converting TBi to old school carb

    OK 2 things: why do you want to use both pumps? One is a low pressure pump and one is a high pressure pump, so for a carb installation all you should need is the low pressure pump second, now this is from memory but I think the power source on the starter solenoid is actually to bypass the oil...

    Why an increase in engine horsepower will hurt your ‘holeshot’, acceleration and midrange cruising.

    certainly could be.... back in the hot rod era usually with a highly tuned engine radical cam, you needed a close ratio manual trans for it to perform. so with a single speed transmission that a boat has, emphasis should really be on torque at the expense of HP.

    Riser To Manifold Torque w/Sierra gasket

    15 years? you must be in fresh water because in 15 years I'd have changed the exhaust at least 2x if not 3x lol. So, I would probably want to run a belt sander on those to make sure there are no pits or slightly corroded areas if you want to reuse them. What we do is usually replace the elbow at...

    Momentary freezing inboard

    also: a small amount of residual water even if it freezes will have room to expand in most cases, if you drained it properly.
