Motor choices/reliabilty can of worms!

Post by marshrat »

In the market for a new ride and seriously thinking about leaving the AC world! Had some questions for those that have them or know.
I have had the opportunity to test drive some stupid powerful boats recently, but I just ride and watch the speedsters!
I want a ride/family/hunt boat 14x8 aluminum hull w/polly pretty basic ,seating for 3-4 450-500hp w/2.3 or 2.68 box.
I do not race or have the need to go 80mph !!!!!
Most of the big builders are pushing the PCM 6.o or 6.2 Ls motors the 6.2 having the supercharger on it and slightly more Hp. Pretty tame motors and I have driven both they seem plenty powerful.
The Big LS guys like Wt,TKE Mast etc are available and slightly less weight with great motors, but again just looking at long term ownership costs. Im looking at it like a daily driver vs a trailer queen maybe thats wrong?
Meaning my Chevelle was always being tinkered with vs my Silverado that just needed fuel,oil, and started when the key was turned and did what it needed to do.
With the amount of $$$ some of these boats are pushing I'm really questioning if I may be slightly crazy for even considering it, just looking for some feedback from folks that have made the choice on powering their boats!
Thanks

Being a CSOB an unable to justify half of what some of those rigs go for,
I will sit this one out and watch . . . as I try once more to see how that is done. :lol:

I am not that far from you. Let me know if you would like to go for a ride and see how an LS performs. It is hard to beat first hand experience.

I recently did what you are thinking of doing. The hardest part was parting from an ac engine I have worked on for several years and that is just it the wording WORKED ON. Either way ac or car engine if you spend you get a good boat if you do not spend you will be working on it. The pros and cons I see so far.

Cons-car engine boat is heavy like a barge.
Cost is pretty high to get started the right way.

Pros-believe it or not it is quieter then my old boat.
has WAY more power-go anywhere and pull a boat with you.
parts well is there a parts store and Jeg's, Summit and the rest of them are a simple click on the internet away and CHEAP.
Stability went up 100% guess it is because it's heavy.
I could go on and on.

Wish I had done this many years ago. To all the parts are getting harder to find guy's----I can now find them even on Amazon. :dontknow:

I have had a three 540's and even went the gearboxed 540 route for a while. Then I had waterthunder build be a 500 hp efi ls 3 that I beat on for 4 1/2 and put a pile of hours on it . It has been an awesome motor I just had him build me another engine and I am sure it will be as good as the last one.

Let me caution you about riding on the LS3 CarMotorBarge he took me for a ride a couple of years ago and it cost me $45,000. reason being I was so impressed I had one built

Lot's of great choices out there :stirpot:

Pick a competent engine builder and you don't have problems.

DIY, mickey machine shop, crate cheapie get what you pay for regardless of platform.

Over and over the lesson is a purpose built engine from a qualified builder is the key to longevity.
