I just got it a few months back....It s super clean and has been well taken care of. Its about 2400lbs. 18'. The prop say's 14 by 21..its super fast out of the water....revs about 800 at idle...speedometer say's about 52 or so with me( 200lbs) and full tank of gas. It revs around 4800 or so....Is that in the range...Also should i be using synthetic oil. The boat is being winterized soon as i'm in Ontario and the cold will be here soon.Thanks.
