What pump?

[old islander]

Boat is a 77 StarCraft Islander
153CI. 120 inline 4 Mercruiser
MC1 out drive
Trim system is dual solenoid
2 dashboard switches one is red, marked in/out one is black marked up/down
Labeled as startrim on dash board
I need to replace the trim pump due to bad check valves. Looking on the iboats site I see many pumps. Correct part # for the one I need?

Re: What pump?

Ok, I found the pump I need. There are 3 that will work. Arco, Sierra, and Mallory. Is any of these brands better then the other? The price spread between them is about 80 bucks.
