Starting my 1986 Four Winns Horizon 170's 3.0L Mercruiser engine for the first time since September 2021. The engine had been winterized and oil fogged last fall and not run since. How much cranking will it take? Let's see.
It always runs rough for the first 30 seconds or so, I think it runs on 3 cylinders, but then smooths out. It's done that on cold starts as long as I've owned it.
Actually I just looked it up. The 3.0 was in production from 1963 to 2015. That's 52 years! They were basically in almost everything up to a certain size boat where it would have been too underpowered for the job.
I don't know as it doesn't have an hour meter. The engine was refreshed 4 years ago with new rings a valve job and new seals. It wasn't a full rebuild but the important stuff was changed.
@@RustyShakleford1 top speed is a little over 40. I generally cruise between 30 and 35. Fuel economy is good. It's only used maybe every other weekend. I fill the 26 gallon tank when I put it in the water for the summer usually Memorial day, and don't need to add more before it comes out on Labor Day. Of course I'm not pulling skiers or tubes, just going for rides and cruises around the lake so I'm not taxing it much. And I'm not out driving it around all day. A trip around the lake is about 7 miles.
