    99 50hp Johnson compression

    Good morning, Im a diesel marine mechanic & considering buying a J50PLEEEA outboard for a boat im building for my nephew. It seemed to run ok on a stand. I did a compression test & the top cylinder was about 115 psi & bottom was slightly more than 105psi, is this acceptable? I also notice the...

    Could you tell me if engine oil coolers are use on gasoline marine engines? And if so can you give me an idea of what size & type. I know ive seen P.S. coolers & fuel coolers. My lack of gas marine experience is showing...I assume if there is one, it would be in-line on the raw water intake side?

    Yeah, I always had big blocks in my Super Sports, squeezing the kind of torque & power out of a small block is a fine line balancing act. I already had so many sbc components I stuck with them. Bigger is Better!

    thanks for all that. Ive had the block bake blasted, magged & sonic tested. Magged the crank,Then turned mains down .010. Ive done all the oil porting & clearance work for crank myself. I made a jig myself & balanced the large & small ends of the rods, rings, pins & bearings. Opted out of the...

    If zero deck now, I wouldnt be able to shave anything off for a future engine rebuid? maybe not even worth holding on to a marine block that long, even if its freshwater cooled? I dont know this stuff, the marine rebuilds I do as to what some people refer to as "in chassis" I can rebuild an...

    What do you think about block deck height? should i zero deck it or leave the pistons in the jug a little & use thinner head gaskets? And what type of composition or material is good for gas marine engines???

    I have to say, i have used your "Enzo" quote many times, Love to see it & I like to live by it. I only work on Diesels, but love to hammer the gas!! Now I"ll stop blabbing

    Wow!!!! What an awesome engine compartment! Did the Rogue come with a nice big opening like that? Or did you FAB work to floor? Great to see a Big Block in there too, that’s the way to go. The exhaust work looks amazing too. Do you have the capability to Tig stainless & where do you get the...

    Gotcha on the boat buy year. If you dont mind me asking...what is a collector on your exhaust & how can it be pulling water from 12' away on a boat your size? Wouldnt that pulling zone be far beyond the transom of your boat? Is the use of the mufflers to keep it that much quieter? Sorrry about...

    Thanks for that info Scott. Yes I knew about the reversion end of it but was reading conflicting articles about the LSA and duration. I was trying to keep my torque curve at the lowest RPM range, but obviously after hearing from you guys the reversion end of it far outways the minimal torque...

    I'll check it out, thanks. I've had my share of glass work & dont much care to do it anymore, especially in New England weather.

    Thanks for the input. Im a little confused on dry jacketed exhaust? I will be using factory Mercruiser manifolds with added closed cooling system, Im assuming that is not dry jacketed exhaust...Ill check out the cams. I am very tempted to make another boat purchase, A 24ft. Rogue just showed...
