    Prop diameter effect and planing trouble

    We are looking and ready to upgrade when the right boat comes along. When that happens, I'll just list it for next to nothing to get it out of my driveway. Considered doing just this, but decided against it because it is a big job, and I don't really know what I'm doing. I've got the...

    Prop diameter effect and planing trouble

    Insurance for me is $140 for the year. I do my own maintenance. Very little cost aside from fuel and towing fuel to be on the water.

    Prop diameter effect and planing trouble

    I know it is performing poorly. Low compression in one cylinder, but we are saving for a different boat and don't want to dump a bunch of money into this one. Was hoping to get some compromise on performance with a prop change to get us by a season or two.

    Prop diameter effect and planing trouble

    Never heard that perspective, but it makes sense. So maybe a 17p 3 blade for towing sports? To much lift? Ugh! propellers are so complicated lol

    Prop diameter effect and planing trouble

    The overloaded boat is a few times a year thing, but still trying to pull a skier out is challenging with 3 on board. I thought going down in pitch would make that better, and the 4 blade design even more so. But it seemed to not be the case with 2 adults and a 7 year old yesterday.

    Prop diameter effect and planing trouble

    I thought 4 blades helped plane faster and hold it better. Is that wrong? Planing is the issue I'm trying to fix

    Prop diameter effect and planing trouble

    So I've been having trouble with planing since I bought my 1987 four winns 195 with a 4.3L. It had a 23 pitch prop when I bought it, which was way too high, so I bought a 4 blade 14x19, which was better (33mph wot with 2 adults and full tank of gas @4600 rpm), but with a loaded boat (5 or 6...

    4.3 motor swap with truck engine

    😂 I sort of feel that way myself. I was not looking forward to the swap, but I have put so much time into it already I feel like I'm invested.

    4.3 motor swap with truck engine

    I couldn't tell what was knocking. It sounded like it was definitely coming from the engine compartment and was loud enough that both my wife and I heard it and looked at each other. It was very random sounding. Not cyclical at all. Just rattling chaotically. Always right around 2000 rpm. No...

    4.3 motor swap with truck engine

    Sooooo....the admiral convinced me to go out for one last hoorah before I started this swap in case I completely botched it. Last season it ran low on oil, and I didn't realize it until I heard a knock mid acceleration (right around 2k rpms before appointing normal again). I was able to recreate...

    4.3 motor swap with truck engine

    So since I don't have a mechanical fuel pump does that mean I can assume the water pump will fit?

    4.3 motor swap with truck engine

    If that's the case, will the water pump fit as well then? I'm planning on starting a bit of teardown tomorrow, so I'll look for a balance shaft and try to get a better look at the casting numbers as well.

    4.3 motor swap with truck engine

    What starter will fit on a new vortec block? my current block has no mechanical fuel pump, so it is newer than the original. What do I need to look for with a new starter to make sure it fits?

    Geez thanks for the catch....That would have been not exciting at all

    4.3 motor swap with truck engine

    I thought the issue with the starter was just the mounting bolts. I must have misunderstood? What will not work with my starter?

    4.3 motor swap with truck engine

    Alright, so I hope I have this right. I am keeping the heads, intake and carb from my old motor due to unavailability of low priced vortec intake and 4bbl carb. I'll hang on to the heads and keep my eyes on the used marketplace in my area. I plan to use the bolts that are different from the...

    They would have marine intake manifolds?

    4.3 motor swap with truck engine

    I can seem to find any for $50. Not sure where to look other than Craigslist and fb marketplace.. I could not get any visual on casting numbers. I'll pray pictures of what I could see. Intake manifold had a stamp 6 on each side, so 12

    So manual trans is a more convenient donor motor?
