    Buying a automotive engine to replace my mercruiser, need opinions

    In addition to the cast impeller a marine water pump is bi-directional not sure which belt configurations drive it the opposite way than it would be in an auto configuration. Normally a truck cam would be ok but I think this is bigger than a truck cam. I think the 230 deg duration @.050" would...

    "Fogging" new VP 4.3?

    I think some folks mix the two stroke and fuel pour it into fuel filter when changing, run it a few seconds. to get oil gas mix in engine. come spring the small amount in the filter is quickly burned off during start up

    Are Merc Mc-1 and Alpha 1 Gen 1 interchangeable ??

    Yes an Alpha one gen one will swap with a MC1 drive. Should be plug and play. Also the alpha drives will be about 10 + years newer than your MC1 drive The driveshaft comment you are hearing is related to inline engines used a shorter driveshaft where it engages the coupler. Shouldnt be an issue...

    Volvo Penta out drive

    Id start by going up 2” in pitch assuming current prop has you in the correct rpm range fir engine. I did a similar swap with a 4.3 mercruiser (1.82 ratio drive) powered boat. PO cracked the block, i swapped in a 5.0 which by the factory would have come with a 1.62 ratio drive. Went from a 19”...

    1995 Searay 5.7 GM winterizing mods..

    High Performance Gear Lube Color - Bravo 3

    I would think that means you have some mositure coming in. I use High perf gear lube in my alpha one gen 2 - after 40-50 hours each season ti comes out the same color as it goes in. I also use it in the jet pump on my sea doo instead of buying the 9 oz Sea Doo synthetic gear lube bottle for...

    Pre Alpha Prop?

    Unless someone swapped the wrong ratio drive on it, verify the tach first before playing with props. Unless the engine needs work/tune up, the hull is water logged would expect a 17" to pull way more rpm than 3200. What is the mantenace hsitory on the engine- I know you said compression is...

    Air Don't Freeze Winterization

    Yep, drain them and i leave the plugs out. Works fine, biggest issue you may see is corrosion on plug threads in cast iron. If you have the newer blue plastic ones this is not an issue

    Fluid Changes for Winterizing, Do I Need to?

    This thread is an interesting take on an oil thread.… Change it or not doesn't matter to me. Personally I do my oil and drive lube annually and the boats I’ve maintained have lasted 31, 25, and current boat is 17 years and counting. Seems cheap compared to the other work you’ve posted about ...

    1999 bayliner vibration

    I would take a look at All Dodges question(post #18) as the way you move the mounts is inverse to what you think. If you had more grease on the alignment witness marks say on the bottom, you actually want to move the mounts up to put the coupler down. Is it possibel you are moving the mounts...

    Strange noise Mercruiser 4.3 VIDEO

    Take the drive belt off and see if it goes away. This would narrow it down Other thought id the spring loaded balls in the T above the thermostat housing. These restrict the flow of cooling water to the elbows. Maybe they arent opening and water through them makes a noise .

    Mercruiser 140 barely running and running rough

    Agree with rick and bondo thats the float bowl overflowing, only thing to add is verify the fuel pressure is ok as too much fuel pressure can over come a otherwise ok needle seat and float. Also check condition of float make sure it is not damaged or water logged
