Johnson 88 SPL identification

[Sundy]

I have a Johnson 88 SPL, and the ID tag is toast. I have pictures of the powerhead and the cowling.

Any help with identification is appreciated.

I did a cold compression test. The results are not good. It runs, but not well,l and the lower unit seems OK. Is it worth salvaging? I burned 6 gallons of fuel over a 3-hour excursion.

1. 110
2. 120
3. 96
4. 100

My photos are too large, so here is a link to Google Photos. Cowl and powerhead

A 1991 model that needs a rebuild.-----I suggest 4 new O/S pistons / rings.-----Lucky you if it is a blown head gasket.

1991. Thank you.
I'm a newbie. What are O/S pistons?
Oh, I think I see. Oversize.
