    saltwater 5.0 weak points

    Luckily, they didnt, and will be replaced before starting the engine up again I would then need to reflash the ecm to update it to 350 spec. Sorry, this aint carb stuff. At that point I may as well build two 6.2s. Also I think the 305 heads wont fit a 350 short block? I do like the closed...

    saltwater 5.0 weak points

    Hello, just picked up another project boat but this one has seen saltwater for 15 years (I think), and then sat for 5 more, it has twin 2005 5.0 MPI engines with dry joint exhaust. My concern is that these are open loop motors. What rots out on these engines first? I will be replacing the...

    I/O (Sterndrive) Conversion to Outboards

    Just wanted to jump in here and say that you will probably loose axius. Merc dealers are often very reluctant to install joystick piloting on repowers, its mostly on new boats. Besides, if your outboards aren't going to be installed exactly the same as in the factory version, you will need a new...

    Anyone try this scan tool?

    Oh, I have diacom for some time now, I was looking for something to extend my capabilities. Diacom is good for diagnostics, thats it. When I swap out an ecm on a 40 foot boat in my yard, I don't want to have to pay to have a 40 foot boat taken to the dealer just to set an engine configuration...

    Anyone try this scan tool?

    Was digging on the internet to try find a copy of G3 (no dice :mad:) when I ran into this thing: https://www.obdstarstore.com/wholesale/obdstar-iscan-mercury-marine-diagnostic-tool.html I am curious if anyone has actually tried it and if it actually does all the stuff that it advertises. If not...

    350 MPI hard to start, runs terrible

    Ok, I managed to get the fuel pressure in check at 32 psi with the pump on. I did take the little screen out, and although it looked clear, I blew it out with some brake cleaner and it helped with the fuel pressure. So I guess it was the screen plus the regulator that got the fuel pressure where...

    350 MPI hard to start, runs terrible

    not sure on what you meant by the codes with a tone meter. As I mentioned, I hooked up my diacom laptop and there are no codes shown there (that is the first thing I did). Also when cranking I am getting a good engine speed signal, so the cps should be ok. I also checked for spark with an...

    350 MPI hard to start, runs terrible

    2001 350 MAG MPI (MEFI 3). This one has me really stumped. Last year, it wouldn't run at all. I replaced all the spark plugs and the distributor cap and rotor, and it fired right up. Come springtime, the engine started right up, but upon acceleration would sputter and blow black smoke. I figured...

    Rinker 282 trailer

    Well, I was reading the replies and remembered what I did in engineering class. Yeah, we used a pixel calculator to get dimensions from three views. I did the same with the boat and figured out the length of the boat that should fit on the trailer. I adjusted my bow stop and drove down to pick...

    Rinker 282 trailer

    Hi, just got a 2005 rinker 282 and need help picking out a trailer. The boat is listed as being 29 feet long. I went ahead and looked at a trailer that was listed as being for a 28 foot boat. Problem was, that when I went to measure it, the distance from the bow stop to the back of the bunks is...

    Outdrive Paint & Prep

    Here is my experience: the alumiprep alodine is generally the best way to go, BUT... Here is what I did last time to paint my seadoo jet pump nozzles (paint stuck really well) 1. Sandblast or clean up the corrosion REALLY well. Brass brushes only, no steel brushes as those could leave metal...

    replacement Chevy engine for volvo penta

    Yes, 100%. I just wanted to be clear in my post to avoid cheap knockoffs, who knows if they are ignition protected. OE GM is fine (they still go bad all the time though, I have fixed a hilarious number of "no start" engines just by swapping out bad crab caps and spark plugs)

    replacement Chevy engine for volvo penta

    I will say something a little different than the replies here and might get hated on, but it might save you some cash. What you have is a "crab cap" distributor, it is a GM HVS distributor. What you could do is go ahead and buy the GM distributor (make sure it is OEM acdelco) and look for a...

    8.1 Gi manifolds

    Hi, quick question. Are the volvo 7.4 and 8.1 manifolds the same? I see them listed for sale as being the same, would just like to confirm here. I bought a boat and I would like to throw in some new manifolds on it for peace of mind. Second question, how hard is it to upgrade the 8.1 from 375...

    yamaha F250 DERATE to F225

    Hello, curious if it is possible to turn a yamaha F250 (3.3L) into a F225. The reason I want to do this is there aren't much F225s around for sale, but quite a few F250s. My boat is only rated for a 225.

    Vinyl ester filler over epoxy and gelcoat questoin

    First question I was trying to find out if I can put vinyl ester filler over fiberglass that I laid up using epoxy resin, not poly resin.
