Well it looks like my 99 OL25is gonna get the M1 put on. Just picked one up that has the crossovers, and regulator with it but no fuel pump. Thinking the aeromotive pump is the one I want.
I have read that new fuel line right from the tank are needed?
Motor is stock with 230 hours and stainless marine exhaust and am not looking for crazy speed just want the boat to run over 70 even if I have a full tank of fuel and 5 passengers.
A few questions...
Does the ECM need anything
Any other fuel requirements
Also, what about thermostat? Boat run 180 degs now
Any other tips would be great.

Aeromotive pump.
New 1/2"min line from tank
no thermostat
ecm recalibration.

Upgraded oil cooler if you want it to live!!

What is done to the ECM? Timing taken out?

How come on the procharger site, they dont talk about sending your ECM out for a new curve? Do they just use the regulator as a band-aide.

yep its just a bandade,if you take the thermostat out your engine wont know its warm and it will stay in cold mode and the idle wont come down,that's one of the things that need to be addressed..call mark,he knows what needs to be done..

Also,look into a 2 bar map sensor also,,sopppose to clean up the FI a Bit,it will have to be calibrated into the ecm,and raise the rev limiter,prochargers like rpm...if done correctly you will pick up 10+ mph with the rite prop..i have seen guys run into the 90's on 22 classics..
