1989 TS6M (sat for 5 years)
First off, thank you to the community for the awesome posts, advice and guidance. Last Sept I inherited my Grandfather's 1989 TS6M. It sat covered in his garage for atleast 5 years and has about 380 hours on it. I prepped the trailer bought new tires and drove out to California (Marine Corps not a hippie)
Started tinkering with it early this spring.
Changed the oil and filter (mobile 1)
New plugs
New fuel filter
New blue top optima battery
Cleaned up the carb
Drained the fuel
She runs like a dream starts right up every time. Put her in the water on Sunday and she ran great thermostat stayed at 160 degrees the whole time.
Questions:
Do these normally burn oil? Not a crazy amount but could definitely smell it maybe 1/4 of a quart. And is anyone else running full synthetic?
How fast are you burning through fuel? We were on the water for maybe 2 hours and went through approximately 15 gallons of premium. I wasn't hammering on the throttle and kept it at about 25-35 mph.
Thanks in advance.

But I suspect any consumption you might be seeing is more a result of the engine sitting for 5 years - maybe the rings are a little stuck... I wouldn't do anything drastic, just run it a bit more and keep a close eye on the oil level. Keep close track of how much you're adding per engine hour on the meter.
And enjoy the boat! I have two 89's in the family, but one does have a much newer engine in it. Not because the old one died, though - they'll run a very long time if well maintained.
Thanks, I was thinking the same thing. It ran perfect in the test hit (Sunday). I'm doing the belts and PCV valve this weekend then heading to Havasu in June. I have a buddy taking a boat out worst case scenario he tows us back lol. I'll have a few extra quarts of oil and a 5 gallon gas can just in case.
It's been a lot of fun to work on and mess with, normally I fix Guns so this is different for me.
