    Volvo Penta overheating

    Did you also replace the #24 “O” ring seal ? Also looks like you need a new bearing in the pump. You might be able to match it up at any NAPA or a bearing supply warehouse.

    Oil in outdrive but passed pressure test

    What you should do is drop the lower. Then you can pressure test the 2 units separately. You just have to plug the oil transfer port. There is a good chance the shaft seal area below the water pump base may be the leak as that is a water high pressure point. The shift shaft seal is also...

    Pay attention to #s 35 & 47. Those are the weak link that SD is referring to.

    1975 225 OMC

    The washers and spring were originally used as a ground to ensure the lower gear magnets a negative charge. Later on there was a stainless ground strap added between a pivot cap bolt to the bolt that mounted the rubber bumper. If you do not have the strap be sure to add something similar. If...

    MCM260 Problem

    You should also check the dwell and timing, it could be possible that the centrifugal advance in the distributor is not advancing due to being stuck from corrosion.

    MCM260 Problem

    In addition to the throttle control sometimes there is an additional hole closer the throttle shaft which will give full open on the carburetor. Does your engine still have the original ignition? Or has it been converted to a points style system.

    1975 225 OMC

    The purpose will be as SD said to keep the oil in the drive cool because the exhaust water is too hot. As long as the impeller blades are still in place is all that is needed to flow water through it.

    Possible trim line snowballing nightmare?

    From what you posted it appears to be aa alpha series. You do not have to remove the engine to replace the hoses. I re sealed the rams on my last boat without removing them. I just removed the rear cross pin then unscrewed the caps and pulled out the rams. Just be sure to use a flare nut...

    Possible trim line snowballing nightmare?

    The block under the gimbal housing is held on with 2 stainless nuts. Sometimes the gasket survives. Pry it down and then you can get to the 2 hoses. What model do you have? Do both the hoses attach to the front of the ram?

    If you add an engine pulley driven pump and draw water through the bottom just connect the incoming water from the drive with a “T” or “Y” style fitting and of course a valve where the hull connection will be. This way you will be able to continue using the flush out on the pivot cap.

    Try to slide the white plastic sleeve off. With a block of wood on the table tap the bottom of the extended stainless down which should drive the cooler up and out.

    Overheating AQ125a leaking cooling sustem

    If the bolts are causing the problem you might need some heat around the head of the bolts. As far as the cover it will take some gentle persuasion with some thin wide screwdrivers.

    Tilt / Trim problems :(

    In the brush head cover of the motor is where the thermal switch is located, it is part of the cover. Before you switch to the used pump spare be sure it does run. The 3 bolts that mount the pump body to the inner transom plate can be somewhat of a problem depending on the boat’s construction...

    Tilt / Trim problems :(

    The most forward port on the trim block under the gimbal housing is the up circuit. On the rams the most forward port is the up no matter which side. There are no right and left rams. You have the hoses crossed. Just remember front to front, back to back.

    Tilt / Trim problems :(

    Did you disconnect both hoses on the ram? The high pressure hose on the bottom of the pump tends to loosen over time.

    Where to buy 1980s tilt trim o ring kits

    Try matching them up at a NAPA store. Also a hydraulic repair shop and if there is a aircraft supply in your area that could be another source.

    Time for my first bellow change, tips?

    The best tool for the job is a 1/4” drive 5/16” universal socket or a 1/4” universal with a short 5/16” 1/4” drive socket & driver handle.

    Re read my post #4. Yes there should be a good supply of water feeding the thermostat housing. I also sent you a private message.
