My inner cooler busted and leaked water in motor. If I take the insert out and use the housing only will this cause any harm? Innercoolers for a 1671 are far and few between . Im thinking this is a temporary fix. Pull out the insert , plug the water lines in the housing and roll on . The river is almost 90 degrees so I dought the cooler is helping very much right now anyways. Will this work ? I dont know why it busted , the top was torn up . Something flew off the blower . But I inspected the blower and it looks fine. Spins free and smooth.

remove it completly, bump the timing back a little, and i think it would be fine.

Intercoolers work on a tempurature differential. If the water is 90 degrees... the air must be over 100. You are still going to cool the charge by running the cooler.

The innercooler is probably doing alot more than you think,the air leaving blower could easily be 250 degrees and inercooler using 90 degree river water at 80% eff is easily dropping air to 130-140 degrees. If you choose to gut it out for now you better drop your boost back a few pounds and pull out a few degrees timing or your seriously risking detonation. Most boats running 16-71's are twins unless some kind of drag boat,you would have some serious drivability issues if you took the inercooler out of one motor on a pair of twins,Smitty

Twin 572 with 1671,s / I cant find an insert to fit. Lee Performance products Brand.

You areprobably correct about the temps. The blowers hold lots of heat. Maybe the cooler line got clogged and the fins melted. they were a mess but only on the top.I put the cooler in the sink and it leaked its but off.

Hinde sight, without the cooler insert the air would be hotter there fore creating a rich condition . Less air more Fuel ????Air quality woud be poor. Or am I totaly incorrect.??

Without the cooler detenation will occur, which will take your good motor and make it into very bad pieces. Detenation is when the flame front from ignition doesn't travel in a smooth and timely manner, but in an explosive, uncontrolled event before the piston reaches top dead center, basically killing the piston, hammering the rods and crank untill something breaks. This happens when the air/fuel charge is to hot, to lean, or has to much timing. You can take some boost out and check/set your timing, for starters, and take it easy untill you get it fixed,remember that one motor will be making less hp causing the other motor to make up the difference ( more work on the motor and drive). Did you put this combination together new or did you buy it used? I would check the other motor (if there is one) for similar damage.

Melinda,

You might want to check with Whipple Industries. I believe they make a replacement core that will fit the Lee cooler.

This here is solid advice!

Call Whipple and get the core replacement it comes in cupranickel and is approx 1200
dollars. This should take approx 4 hours to fix.
I have lee intercoolers with these cores.


Fix it right and call it a day!
