Transom, compatible?

[WhatdoIknow]

Hi,

I have a 1999 Tahoe deck boat with a 5.7 Mercruiser Alpha II that was not winterized and had to pull out both off boat.

I have found a 1988 5.7 Mercruiser with outdrive, complete drop in.

What challenges will i be facing as far as the year difference?

Thank you!

Nothing much is compatible between the two. But taking the entire older setup - engine, transom assembly , and out drive and putting it on your boat would work without any real issues

Ayuh,.... Welcome Aboard,..... Maybe some wirin' or plumbin' changes, should be plug, 'n play,....

The 2 extra holes in the transom will still be "Covered",....

What is wrong with the Gen II drive? There isn't much to winterizing the actual drive. You could use the 1988 5.7l and still keep the Gen II unless there is something wrong the drive. It might take some parts swapping though.

Thank you for your fast response gentleman!

This is a boat I recently purchase and some how engine and outdrive are damaged.

Howdy,

How about a little more detail? You might be much better off replacing the drive with an SEI GEN-II and fixing the engine.......
