I thought I already posted this but do not see it so sorry moderators if I double posted...

New to the form and I have a 91 Glastron Sierra 195 with a 4.3L Merc, Alpha One Drive and currently running a 21P SS Prop.

Boat has been running great for the 5 years I have had it, regular oil, gear oil changes, heated winter storage, and never left in the water when not in use (keep it in the garage when I am not at the cottage) and well taken care of. Boat is in Ontario Canada in the Land O Lakes region so no salt water either.

I saw a few posts with links to the service/maintenance manuals and was looking for one for my engine so I can get into some of the maintenance items above and beyond fluids.

Not afraid to wrench as I work on my sleds (Snowmobiles) and mod up my 2008 GMC crew cab 3/4ton diesel, just not familiar with the marine side of the GM engines or what other maintenance should become part of a regular routine. So any tips/maintenance items would bbe appreciated. Just changed starter soleniod as well and cleaned carb this past weekend.

Here is a pic of the engine, if any other serial numbers etc are required I will have to get them this weekend while at the cottage. Ownership says 91 but I noticed the serial number on the boat has a 90 in it so not sure if the engine is a 90 or 91.

Since this shows as your first post, you most likely clicked the wrong button, I still do and I've been around for a few days more than you.
You're going to need some serial numbers for your engine and drive to find out for sure what year they are. Between 90 and 91 a lot of things changed, including manuals.

Engine manual #7 is the proper manual for your engine, the drive is what changes. Here is the manual for the engine.
