how can i get more power from my 99 model 90hp yamaha aeto

[redyute]

I ran two boston wailer 17 footers with 90hp yamaha motors,the boats are used strictly for watersporting activities, and now i have lost good power from one of the engines.They are only four years old and i was wondering if it was time for an engine reduild,or if there was something i coulod to get back the normal power that i am used to.

red- have you tried 'decarbbing' the motor ? that is a process of removing the carbon build-up from the piston rings,top of piston,cylinder walls..etc..this is accomplished by using a fuel additive such as Yamaha Ring Free...but there are various products that do it

Hi, Redyute.<br /><br />Can you be more specific about what "lost good power" means?<br /><br />You may have carbon buildup screwing up compression or you may have a fuel or ignition problem. It is not very likely that you need to overhaul it.<br /><br />Do as ZZZZZ suggests and do a compression check.<br /><br />Give us more details and we can surely get your ponies back.<br /><br />Good luck.

Is that a 2-stroke or a 4-stroke engine?
