I need help getting a close Id on this motor so I can buy a rebuild kit, however I know it's been messed with over the years by someone other than me. So here's what I know.
it's supposed to be a 94' 90hp sportjet. the only thing I'm sure of is it is a sportjet.:redface:
1)the sticker is gone
2)it has carbs that have bi-pass tubes md#top 826116,middle 826117,bottom 826118----started this in 95' i think, but these numbers don't show the tubes either?
3)it has bullet electrical connectors on the switchbox
4)it has a switchbox that sits more vertical than horizontal.----again 95'ish
5)it has a red stator upgrade done
6)it has a threaded impeller--94'
7)it's been bored .030 over
8)it has a melted top cylinder
9) the hull number is BUJ76365B494

So heres what i think. It is a 94' but has 95' carbs mounted and the electronics updated with 95' switchbox mounting plate and electronics OR it's a 95' powerhead on a 94' pump.
So any ideas would be great.

So could anyone tell me if there were internal changes made between the 1994 and 1995?

so I guess if the # stamped on the rod begins with 640 it would be a 95' and up and if the # is 335 or 600 then it is a 94' and below. The difference being top guided pistons in the newer versions and bottom guided on the 94' and below.
