carb to MPFI

[TKDfun4u]

So im new to this forum, little back ground on me. I have been an auto tech for 20 plus years and a shop owner for 6 now. Id like to find a complete mpfi setup, harness, intake, rails, harness ecm, 02 if that model has it etc. Any idea where I would find such a beast?
I also have my used car dealer license, and parts purchaser license in MN. I have been trying to find something on ebay, or a wrecked boat at auction. Any thoughts?

Welcome aboard

Most find the cost for this conversion gets to be at least a third the cost of a new complete engine.

But yes a wrecked boat or blow engine is your best bet for a OEM setup. Try your local marina or boat shop.

Holley and others make a marine throttle body bolt unit.

ill check into them, around where im at not a huge amount to choose from in way of marinas. I have seen way to many issues with after market efi in the auto world to really want to go there. OEM is what Id like to stick too. Guess I will have to keep digging

What is your concern with stay with a carb? IMO I would run the carb until it's time to replace the engine then go with a new merc complete engine.

I agree ....keep the carb engine until it' shot and replace with an MPFI. I did it 7 years ago on my 1995 2400 SCR and never looked back. I have a Mercruiser Horizon 350 with FWC. It is as dependable as your car engine and never any issues with starting etc. The performance, dependability, and fuel economy is far beyond anything you would get with any carbureted engine. I have had no service problems at all at almost 400 hrs. now

Thanks for sharing Calguy, I also have 2400 SCR and love it and planning to keep it for a while until I need to change my carb engine and do the same you did.
