As you can tell from my join date, I have been around for a bit but have not posted in a while. I previously had a 1988 19' WellCraft I/O bow rider with a mercruiser 165. I used it for two seasons (NW Indiana) but sadly had to sell it to help with a down payment on my new house. Said house is lake side on a smallish lake. I was trying to save up to get another boat but my neighbor offered to sell his boat to me for what he paid for it if he could use it a few times a season to tube when his family came to visit.
So I took him up on it and purchased a 1983 16' glastron GX150 with a 88HP Johnson OB for $1200. The tach, speedo and trim gagues do not work and it's not the prettiest thing in the world but it tops out at what I would guess to be 40-45mph. I have a GPS and can use that to get a real number. The OB seems to start fairly easy and idles fine after about 30 seconds on fast idle.
He said he winterized it by draining and replaceing the oil in the lower end and trimming the OB down and letting the water drain from the exhaust. I know in IO's you need to pump antifreeze through it as part of the process but he just replaced the drive gear oil. Is this proper winterization for an OB? Is there anything else I should be aware of with this model/year boat and motor?
I am very happy with my purchase, just looking for any information I should be aware of.
