I have a 1978 Seaswirl with a 140hp mercuiser motor, 4 cyl. Appears my trim motor may be shot. I bought the boat last month knowing it needed some repair. I found they had the trim selenoid (single selenoid system) was wired wrong and the selenoid was bad. I replaced the selenoid and wired per the digarm and was able to get motor to go up down a couple times (seemed a little slow, but was working). Day later I pulled out of garage to hook up to hose and start engine, but found the trim pump would not bring motor down. Ended up removing the hydralic hoses going to cylinders on engine and appears the oil coming out has water mixed in. Went though process of draining, refiling, etc. When to run trim motor again to start bleeding process and now motor don't move. I hear clicking noises, but seems pump is frozen. The wires going into the pump have seen better days as well. Was thinking I should just replace it. The number on the side of pump is 79271a1. I found the below in the iboat parts store, but it says it replaces 79271A4. Any one know if Would this work for 79271a1 as well? I have not pulled it out of the boat yet, so not sure exacly what the bolt pattern looks like on the mounting bracket to compare to picture.
Here is the one I found:
Power Tilt & Trim Motor - Sierra
Part # 18-6763 - Replaces MERCURY MARINE 79271A4
