    1998 Volvo/OMC - When shifting to forward, the motor stalls. It runs fine on muffs.

    Those hoses can be tough to get off, I use picks made to remove radiator hoses & silicone spray. Slide the lower hose down the Y pipe….With the everything in place you won’t be able to feel the flapper pin it’s behind the lower hose you see in my pic above…

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    That much for gaskets? Well maybe the consolation is they have lasted this long it seems, problem being even if there are no leaks, no way to determine if they are clogging unless you take em apart. For the 8mm holes I'd suggest a specially calibrated coat hanger wire to rod out those holes. I...

    1988 candia 180 4.3

    On these the timing is set very conservative, 6* BTDC but with 89 octane fuel, with 87 you’re supposed to set it at 1* BTDC. Centrifugal advance on that Prestolite is only 12* @ 3200 as per my OMC shop manual. So even with 89 octane fuel you’re only getting 18* total.

    Power Steering Cylinder Replacement

    The other alternative to pulling the engine is to see if you can find a fiberglass shop that could make the rear enclosure removable with quick disconnect fasteners like race cars and small airplanes use. Pulling an engine just to change a starter or a steering actuator is a big insult from...

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    I thought the same thing Ted, have the risers ever been off? If not it could be something like that. Is the exhaust on these newer Mercs cast iron or aluminum? I never checked my brothers 4.5 when he had one. He had one mild overheat (simple solution rod out the water intakes) but that was...

    Power Steering Cylinder Replacement

    Unless that rear engine enclosure is removable you’re pulling the engine. I did this job a few years ago on my OMC Cobra, my boat is old school so it all comes apart. Had to pull the rear seats & remove the exhaust on both sides. Removing the cotter pins for the mounting bolts was very...

    1988 candia 180 4.3

    If it came with a 15x17 could be an OMC Cobra, that’s what mine came with with the 4.3-4bbl. If your max WOT rpm is low a general check up is in order, for the 4bbl models the rpm spec is 4600-4800.

    4.3 l mercruiser one piece exhaust manifold temp senor install

    If you really want to monitor temps just get an IR temp gun to leave on the boat, that’s what I do.

    4.3 l mercruiser one piece exhaust manifold temp senor install

    The engine is 24 years old, and those manifolds were only made for 3 years because Mercruiser couldn’t get the wall thickness consistent so there were a lot of failures. When that happens it will let water in the cylinders which can ruin the engine. Merc & Barr both make conversion kits to...

    4.3 l mercruiser one piece exhaust manifold temp senor install

    Those are prone to failure due to casting flaws, I’d get rid of them & convert to the 2 piece system before they hydrolock the engine

    That would be the cheapest repair of all possible causes!

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    Isn’t Marelon plastic? Yeah every year I think the same thing last year with the I/O and just keep fixing it! Have thought of a much newer outboard boat but given I’m turning 70 in the fall I don’t know I’d get the use out of it for it to be worth it with our short season….

    Flushing Sea Ray 250 Sundancer in salt water... How To, and is it necessary?

    There was a guy on the Jeep boards I frequent who boated in Fla and he added that Volvo neutra salt system and he said it definitely extended the life of this manifolds & elbows.

    1998 Volvo/OMC - When shifting to forward, the motor stalls. It runs fine on muffs.

    Well it’s not a hard thing to check but it involves loosening the clamps that hold the rubber exhaust hoses to the elbows, 90* down pipes & Y pipe. Then you can remove the in 90* down pipes & see the top of the Y pipe if the flappers are there it will be obvious. If not but you see the rod they...

    3.0 exhaust manifold over heats

    And the why and wherefore of "warm" vs "cold" manifolds which I was able to experience directly, while fixing another problem... So for the longest time, I have heard the statement, you must run a 140* stat in salt water or else salt will clog your engine. Not true in my experience but I'll get...

    3.0 exhaust manifold over heats

    That would actually "bypass" the elbow and the water goes straight into the exhaust pipe!
