I have the exact same set-up on my 1987 18'Outrage that you are considering with a Yamaha 115hp. I purchased the boat in September 2002 with a 2001 trailer for $7,600.00 The boat was in poor cosmetic condition, but structurally and mechanically was and has been a gem. After a lot of sanding, compounding, waxing, and other manual work and purchasing OEM rod cushions from Hall's, along with new boots for my forward shelter and bimini/flytop and a new stern seat from Art's the boat now looks and runs great.
My Yamaha 115hp is a 1987 and runs as strong as can be. The engine had a new lower unit installed by prior owner which happens to be a counter-rotation (lefty). Other than a carb re-buid that I had done when I purchased the boat, I don't have any complaints and haven't had any problems with the engine or this setup on my 18'. I think that my use of Techron and Valvtech De-Carb since the carb-rebuild has helped avoid further gumming or other problems.
My top-end is 40-41 mph with perfect water/wind conditions and 37+ in any condition.
I run a 13 1/4 x 17 stainless Stiletto (as stated above the engine happens to be a left hand rotation). If you want any further details about the setup of the 18' Outrage feel free to drop me an e-mail I would be glad to return the favor that so many other members have given me.
