(Not a Boat Question?)

We just bought a 1988 regal boat with a 165 hp mercruiser inboard motor. The motor needs heat exchangers. How much money are we looking at - Also the guys in the family have replaced motors in trucks; is this something they can do themselves?

Customer (name blocked for privacy)

Status: Closed Value: $15

This engine only has 1 exchanger. Is the existing exchanger missing or froze and busted? Is it overheating? Here is part number and price from Mercury on exchanger:

99438A1

HEAT EXCHANGER

$863.55

Hope this helps!!!
