Hi guys i am new here and just got my first mud motor. its a 27 hp kohler mud buddy and it runs fine when your going slow but when you give it the gas the prop try's to come out of the water and i have to constantly hold a lot of pressure on the tiller handle. i am not a small guy I am over 200 pounds and i really have to get under it to keep the stupid thing in the water. i drove it for about an hour today and felt like i had been to the gym. is the some way to adjust this. does it have something to do with the cavitation plate?

Bend the cav plate up

When .y prop was wore out it did tha same thing. I was about to bend tha cav. Plate until tha new prop fixed it

how can you tell you if your prop is worn out. i have a new one on the way. I went a head and bought one i figured i would have one as a spare but i have not gotten it yet. also where can i get a kill switch it looks like mine does not have one.

Measure at tha widest point and compare to tha 1 u just ordered. As far as a kill switch goes I'm not sure but mudbuddy should be able to get u 1

X2 on new prop and bend the cav plate up.

You can pick up a kill switch at a local autoparts store. Western auto sells then. Also can buy on eBay. I know that I wouldn't use it until you install it. Also it does absolutely no good if you don't wear it. I hook the little wire latch onto one of those rubber wrest bands that you can buy at just about any gas station. Its so much easier to just slip it over your wrist than keep clipping that hook on and off every time. Good luck and I'd only bend maybe the last 1/2or so with a crescent wrench. All the way across the tail end of the plate. (Remember it doesn't take much at all to make a big difference)

Good motor! I have a 2004 27 HP MB. All previous posts are good advice, especially coupe's admonition about getting a kill switch/lanyard and wearing it! I noticed a lot of rust on the prop nut end. Very soon you should try and remove prop, clean threads, apply anti-seize, and then replace. Replace nut/washers if needed. See posts on new owner wanting advice for some simple "upgrades" this forum. My MB LT came with a "trim tab" mounted on the trailing edge- it is bolted on and I bend this up/down accordingly each season. You may investigate if MB supplies them, makes this adjustment easier IMO. I see that is an excel hull- what size may I ask? Good mudding!

This is how I had to bend mine, can't imagine this helps its performance any but I can now let go of the handle while running WOT.
