injected 202 ski boat

[bluejinx202]

this is my M1 seacraft built in nov 1986 by Jeff Tull. it has a 202 with extensive portwork, big valves, roller rockers, solid cam with 500" lift rev range 4000 to 7500 RPM. balanced and blueprinted bottom end high comp pistons, starfire rods, custom extractors with water injection. The engine uses the standard vk ecu at the moment, but i'm just about to run in the new engine with the proven and pre set ecu, then will work on converting to the delco.

i like it

do you have any problems with the extractors being that close to the wood ?

you got any vids of her running ?

Water injection keeps the exhaust temps down pretty well usually.

Does it jsut run raw water, or have a heat exchange?

[Holden202T]

interesting to see the o2 readings in the exhaust

looks like hes injecting water into the extractors to keep them cool .great boat should go pretty damn good
