Re: 115 HP 4 Stroke Yamaha
Hi,<br />I have one Yamaha F115 4-stroke 2003, so I have used mine for 3 seasons now (I live in Sweden, rather short seasons here from May/June to end of Sept usually).<br />So far no problem. I use it in freshwater only.<br /><br />Some have posted problems with "making oil" on F115. <br />Yamaha had issued a service bulletin on the subject. There is an "upgrade kit" for those that need it:<br />- hotter thermostats, <br />- new ECM, <br />- different spark plugs, <br />- a new dip stick<br /><br />My F115 does not need that kit.<br /><br />I'm happy with my F115, no problem so far except I need to grease the top on the Power Trim pistons a few times in the season.<br /><br />Other then above making oil I have not heard of any problems with the F115 (later models), not here or in any other boat/outboard forums I read.<br />The F115 was released in 1999 so it has been on the market for many years now.<br />In 2002 they made some cosmetic changes to the cowl/decals and in 2004 it was CARB 3-stars approved (It was CARB 2-stars before). For 2006 models I belive it is Yamaha Command Link compatible and possibility to use new guages etc.<br />But in general the F115 has been basically unchanged since it was first released on the market in 1999.<br /><br />Probably time to change impeller now on a 2003 model (I will do that this year on my F115 2003).<br /><br />Good luck.
