    Volvo penta 5.0 OSI current drain

    Agreed if the diodes in the alt are bad then it will pull current from the battery. Try disconnecting the alt and watch the meter.

    Volvo Penta Sx-M 1.97 Gimbal bearing + Transom Seal

    Agreed you need to replace the gimble housing, for sure, is your rebuilt motor already installed? Because getting at the mounting nuts on the inner transom plate can be very difficult (perhaps not impossible though) with the engine in place.

    Replacement motor going in ,need opinions

    Well you can do it that way, use it and see if you really notice the difference in power between the 2 engines. If so use it that way for a season and then get a set of Vortec heads and intake for the other engine. If that engine is original it might need the heads freshened up anyway. You're in...

    Surge brake

    And if you have drum brakes I like to grease the adjuster threads with Evinrude triple guard grease and the same on the pivot points for the shoes. In addition there is a new design wheel cylinder being made by UPF. These are a bootless design that can’t trap water like the boot style. The boot...

    Starter rusting out Volvo Penta

    You must be getting way too much water in the bilge, if you are rusting out starters. I have an ‘88 FW that’s been on a salt water mooring for 15+ years and I’ve never rusted out a starter except one year when a cooling hose popped off at the transom & flooded the bilge.

    What´s the best replacement for AQ271C (or 570) 5.7 GM engine, ideally stroker?

    Firstly if the engine was already run in salt water you can't add a H/X because the cast iron flaking rust will just clog it continuously To accomplish what you want you can buy new, just get a new Vortec 5.7 and add the H/X in salt water use. I don't see any real advantage to aluminum heads on...

    Replacement motor going in ,need opinions

    Its easy enough to check, your 1988 pre vortecs have the 12 bolt intake, a 2003 will be a vortec 8 bolt intake. If your other engine is still good I think you're better off getting a 5.0 reman to match it.

    Replacement motor going in ,need opinions

    On your 1988 is the carb a Quadrajet? If so they use a well type choke which works with the pre-vortec just fine (these have an exhaust cross over in the intake to heat the choke & carb) but there is no exhaust cross over for the vortec heads/intake. So you'd have to either figure a way to...

    Riser Extension Blocks - Full Closed Cooling ???

    Yep Ted that's good old salt water...so far my original OMC Y pipe looks very good but I bought a beautiful fresh water used on on ebay just in case.

    Quiet ticking noise

    Ok yes read your first post too fast lol. You might then wind up having to re-adjust the travel on the hydraulic valve lifters. Its a little confusing at first but not hard if you take your time. The exhaust will have to come off to get clearance to remove the valve covers. I did mine when I did...

    Quiet ticking noise

    If you don’t have a mechanics stethoscope I’d get one and try putting the probe on various areas and see where it’s loudest. Try it on the valve covers (valve train) and on the exhaust manifolds (exhaust leak)....

    MerCarb adjusting after rebuild and question about base gasket

    If there is no place to hook up a vacuum gauge you can also use an accurate digital tach to set idle mixture.

    Overheating after impeller change

    Ok on the Volvo if any impeller blades came off they could be lodged anywhere between the impeller housing and the hoses for the manifolds. I would take off the thermostat housing remove the stat and check all the water passages make sure none are clogged. Install a new stat in the housing (it’s...

    Rochester quadrajet

    Another issue with the QJet is when the secondary air doors open. If they open too soon then you get a stumble. On the QJet the actual secondary throttle plate is mechanical but the air doors above them are vacuum operated. There is a spring adjustment that controls the opening of the secondary...

    Trouble reinstalling pre-alpha drive

    If you're over 40 and/or have a bad back and plan on owning I/O boats for some years this drive jack and the alignment tool are two things you MUST have. Because with out both there will be times where that drive will fight you trying to get it back on, both have paid for themselves many times...

    1986 Mercruiser 470 Starter & Fuel Pump

    The big Delco style starters had screens in them like marine distributors do. These do the same thing as the flame arrestor on the carb; if explosive fumes get into the starter the screen prevents ignition from spreading to fumes in the bilge. The small PMGR starters are sealed by design and...

    Trouble reinstalling pre-alpha drive

    Agree with all of the above and what really helps is to use an outdrive jack and get the bell housing and drive on the same plane with each other. You need to be able to hold the driveshaft as straight as possible as you guide the driveshaft into the bellows and then into the gimble bearing...
