I'm sad to see you give up on them. Did you get the drive issue on the boat sorted out?

I do not know if it was a drive issue or a motor issue. One of the motors was losing its fire so it may have been dragging the drive creating this problem.
I have now found the EFI problem I was having with that motor also. The ECU ground was cut so it was never grounded. I’m not going to use the EFI since I have already purchased my Intakes and carbs.

These would make nice upgrades on the 525 Merc's. I may break these down and sell the Tec-3R's separately.

What ecm's come with these? Also what size injectors?

Bocsh 50LB Electromotive Tec-3R with all extra long plug in harnesses.
Thanks Ken

Do u know who tunes those ecm's?

I just noticed you are local. I have a guy Ricky in Annapolis. You can come by and take a look at everything if you like.
or call my office 301-218-7920 E 201
Thanks Ken

Also the tunning is going to be very little required as they are BBC and already tuned. maybe adjust the fuel if your motors are smaller.
Ken

I'd have to use bigger injectors and get a tune but ill give you a call tomorrow.

What size motors are you running that would require larger injectors?
I was told at 3bar the 403's have enough flow to support 110HP a piece thats 880HP
