If you cut through all the crap and see what most of these small motors are really doing then you are in the ball park.

As was said earlier, you are probably about where you should be. You could put a tach on it and make sure you're propped correctly.

Weedeater's 25 is a long way from stock and so are 40's running over 40.

Don't be, its very scary!!! I was coming down the ship channel one day, passing a guide boat and caught a head wind......boat left the water!!!! Scared the crap outta me!! I'm sure those guys got a good laugh. Ive since changed the prop, but still have the big one for the thrill seeking days!!

I really want more than what a 25 will do. A guy I work with has a 40 nissan with 50 carbs and all the other stuff on a 1548 southfork with cmc trim and he runs 40 with two people and gear in the boat.

to be honest my motor runs no differnt now then before I had my carb work done, the biggest gain was my exhaust being opened up. If I would be willing to sacrifice the life of my motor and have it port, polished and head shaved it would do alot more but right now all I have is a 25hp 3 cylinder with 40 carbs that are restricted in jets due to me not wanting to do block work but if I wold have more done this motor would most likely see 40mph but then agin I bought a 200hp on a boat so I could go fast if I wanted and save the life of the 25 for what its made for.

You could get Danny Thibodeax in the Bluff to modify your reed plate if you had the metal reeds and stops still. He's done a lot of motors like yours and they run really well with that modification alone and no change in motor life. My 30 yamaha with the reed plate alone was running 32-33 with just me in the boat and negative trim.

You don't need bigger jets. Danny could really help you out on that motor.
