 25 hp Kohler engine Knocks Hello all, I'm fairly new to mud motor scene. I can tell ya i'm hooked. My 25hp kohler LT has developed a knock at WOT, only when boat is loaded with another hunter and gear. Has anyone ever dealt with this. It dosen't do it with just me in the boat . Any thoughts would be appreciated.

Re: 25 hp Kohler engine Knocks You sure its not spark knock? You should switch to premium fuel and see what it does. My 30 Kohler spark knocks a little even with premium fuel. It was terrible with regular fuel!

Procrastination is a lot like masturbation. Sure it sounds great at the time but, in the end your only f--k--g yourself.

Re: 25 hp Kohler engine Knocks The Knock sounds more mechanical to me. Sounds like someone hitting the engine block with a hammer every couple of seconds. I can ease up on the throttle and it goes away. I will try the premium gas though just to see......

Re: 25 hp Kohler engine Knocks Thanks everyone for the tips...Seemed the premium gas helped. Was worried there for awhile.
