88 Ts6m engine replacement

[RickV]

I have a 88 Ts6m and would like to replace with a newer lighter engine. Preferably EFI with aluminum block /heads/ exhaust or convert to Electric. Any suggestions.

I am surprised no one has chimed in to offer you their advice yet.
That said I Would start by contacting SkiDim and discuss your thoughts with them.
They have no doubt dealt with this issue numerous times , sell the new models of PCM engines and transmissions, and could point you in the right direction.

Convert to electric?????? What are you going to use the boat for? Fishing? Run time would be the issue let alone power to weight issues. Plus with all that battery weight the boat would be a like a lead sinker, actually it would be , straight to the bottom, and the environmental issues, a whole other can o worms. Jmo

why reinvent the wheel , drop a 400 hp 400ci sbc or raptor engine in it. They are fuel efficient and all the power you need

We run sets in the morning early and electric would be nice and quiet, run time might be an issue, possible cost, it was just a possible option. It has been done check it out https://www.youtube.com/watch?v=2UbTAb

I'll give them a call. Thanks

I looked into the electric option quickly a while back, as I rarely run more than 2 sets a day on my boat. In this case there are some pretty good advantages; quiet, charges while it's sitting at the dock, no more transporting gas, and the weight would be about the same as long as you didn't want longer runtimes. Nautique made a prototype a year or two ago, and it seemed to work pretty well. What I found when I did my reading was that to do it right, it would cost a fortune. The Nautique had 2 motors and those things don't come cheap. There was a short thread on an electric car conversion forum on this same issue, it would take me a while to find it, but the bottom line was you would need a lot of batteries to get more than a couple of sets per charge, so in that case weight would definitely be an issue. Personally I think an all aluminum custom built motor with good mufflers and and FEA exhaust would work out much better except for the refueling issues. I don't really see EFI as all that necessary I like the simplicity of a good carbed motor myself, but that's another debate.

Thanks that helps a lot, I really would like to try the electric motor for all the points you made and one more no more winterizing. I think it's out of my reach realistically. Going to start looking at aluminum engines.

There are a few questions you should ask yourself before making any modifications to a supra comp these are great ski boats right straight from the factory. First on my list would be how much money am I willing to spend the second should be how much time I'm willing to spend. I'm speaking from experience aluminum GT 40 heads and manifolds look cool will wake the motor up just a little bit but in the end you will not notice much of an improvement over a well tuned stock 351. I'm speaking from experience of all of the modifications I've done to my boat over the years I would say having the motor balanced was my best dollars spent. I think if you want to make the boat lighter you're better off leaving someone on the dock, ski with less fuel In the tank, or maybe carrying a smaller cooler.That being said I hope you go forward with your plans and modifications. And please post your progress.
