i have a 1984 vip boat with a mercruiser drive last couple years ive had alot of problem with trim pump raising but not lowering pump runs fine both directions just wont go down i take it apart a few times clean it mess around for a few days and finally get it working this year ive had enough of it but cant seem to find part number for replacement its the square bottom pump all aluminum with valve body on bottom with 2 lines on it. ive been looking at a few pumps and really dont see any difference other than side fill is on. or steel or stainless steel mount all seem to be the same pump maybe have to come up with adaptors thanks guys for any help also i did pull my old pump and cant find any part numbers
