truck motor swap problems 4.3

[charlesahtesboats]

i'm trying to figure out just how bad i messed up.
i've got an 07 bayliner. i bought a truck motor to replace the boat motor. i dont know exactly what year the truck motor is. 99-06
the issue is the timing cover from the truck motor has a different bolt pattern than the boat one. and is needed because of the difference in harmonic balancers.
is there an alternative timing cover that may work???

edit i think the truck timing cover will work okay.

Would keep the balancer and covers with each long block. You may have some mix and match issues with pulleys but folks have done the swap before. A couple guys on Iboats forum went through same chit.
