LOTO 500EFI upgrades
Debating on what to do over the offseason. Sell, re-power or upgrade current power. If I re-power 500EFI's, has anyone has a good experience with anyone in the LOTO area? Don't have a trailer so I have to keep it in the area but am looking for a shop that has experience in doing this.
In addition, what can be done to get more juice from 500EFI without losing reliability (new heads, cam, etc??). I would also like to stick with my XR's, everything has been bulletproof to this point, knock on wood, but am getting the speed itch...

I have a set of Whipple stage 2's that are about to come off of my 500 EFI's.... They made an incredible differance with no adverse affect on reliability or idle. I am going to a larger/ heavier boat so I am going to 598 or 632ci engines. The Whipples have less then 20 hours on them. Whipple claims 740hp I would guess it was more like 670-680hp. I will swap ECU's since I had Whipple reprogram mine. Systems are complete (might need some new hoses to reach on a differant boat) and ready to GO! I'll make someone a great deal...... Thanks, Rob

Not sure who to contact at LOTO.... but Innovation Marine in Sarasota FL has some good tricks for the 500EFI. Mine dynoed 550HP after they were done with it: milled and ported heads, cam, and computer program.
