    Impeller housing overheating

    Well if you stay out of shallow sandy water I’d say they are good for at least 3 seasons if you use OE. Each year when I start mine up I judge it by how much water is exhausting under the transom mount. Did you use GLM or Sierra?

    Impeller housing overheating

    I think what you might have experienced was the slight mismatch between an OE housing and aftermarket impeller or vice versa. Start out with all OMC original parts and you will not have that problem again; I haven’t and I’ve owned this boat 18 years and probably changed the impeller at least 4...

    Impeller housing overheating

    here's some pix....OMC actually changed to this design in 1991 or so, then during the joint venture with Volvo 94-98 they both used it, and after OMC was totally bought out by Volvo they continued using the same design till the exhaust was changed when cat converters became required. Those 90*...

    Impeller housing overheating

    About the conversion...the issue with the one piece design is due to the difficulty in casting them sometimes the wall thickness is irregular and so thin they can crack or rust through easily. With the result that you get water in a cyl. Same thing happened with Mercs one piece V6 manifolds. I...

    Another winterize question

    Interesting Ted! I put a gallon of -50 and -60 in the freezer set at zero*F many years ago and found they both get hard; the -100 stays liquid. In fact West Marine which sells all 3 does not recommend -50 or -60 for temps close to or below zero. They recommend only -100 for those temps. So I...

    Another winterize question

    and that's the $64,000 question.....does it really protect cast iron? Apparently Merc thinks so because they either recommend or require that the seawater side of the cooling system be filled with marine antifreeze. Never seen a test of this though. I do know that if I keep spraying my trailer...

    Another winterize question

    You can use the Camco style kit if you have closed cooling as long as the flow is pressurized with a bilge pump or similar, it will fill the raw water side of the heat exchanger & exhaust system (manifolds + elbows if half system, elbows only if full system) with antifreeze, if you are in an...

    Impeller housing overheating

    possibly easy to clean out suggestion: get an OMC factory shop manual. I have the same engine as you and have used the manual every year saved tons of money. BTW do you still have the one piece batwing exhaust manifolds on yours? If so and you are going keep the boat consider up grading to the...

    Impeller housing overheating

    Who makes it? Sierra or GLM ? I"d try ordering an OE OMC/BRP housing and impeller kit. I never had that problem with theirs.

    Impeller housing overheating

    when the hose is disconnected water should flow out, and when its connected it should flow out of the end of the hose Sometimes what happens is people mix and match OE and aftermarket parts. If you have an OE housing, use an OE impeller kit, if you have a Sierra impeller kit use a Sierra...

    Volvo penta Mechanical fuel pump

    it would help if you have your volvo penta model number, that is a start at least but the standard marine mechanical fuel pump is what you need on the Chevy V8. Keep in mind this is operated by a pushrod that runs off the camshaft, these can be a bit tricky to install.

    Impeller housing overheating

    You're saying you get flow up to the impeller mount when you install your water muffs, and then when you start the engine, the impeller overheats? well one possibility is the that little nipple on the impeller housing, (connected to the hose that plugs into the gear housing) that has to be open...
