Hey Red, thanks for the reply. I have never seen an SEI before. No this is not a doner boat, just a project I got a year or two ago, gonna try to get it fixed up and sell so I have some cash, to throw at my scimitar.
For anybody looking for a boat it's a 2000 Ebbtide 188 Champion, has 4.3Merc. and evidently a SEI out drive :) It's for sale!!
That's an SEI drive, an identical replacement for the Mercruiser, good stuff
The gear ratio is the big deal, for your boat, you need a 1.50 ratio, if this is a doner boat you are looking at, you must know what motor is in front of the drive, if it's a V-8 then it is most likely a 1.50 ratio
If it's a 4.3 motor, or smaller it has a low ratio, not all that good, you can run a 1.84 ratio or a 1.65 with no problem
by using a larger prop. but the speed index will be comprimized.
I know it is not a scimitar, it's not even a glastron, but I need to know what out drive this is. The Boat is a 2000 18' Ebbtide, I know it is a Merc. but that is about all I know.
