Ahhh, the factory lists the max HP as 35 and the Coast Guard plate says 30. These are in fact very believable numbers to me. With the 50 and two people and two dogs in the boat, it easily gets on plane at about 1/4 throttle. I've never had it above 1/2 throttle; 1/2 is FAST ENOUGH.

I was kinda wondering if someone was going to say "a 20 is lots".

There's nothing wrong with the transom. It's just got extra holes in it from previous engines, all well repaired.

But the motor weight is too high.

I added a little Torqeedo as a kicker. To install it onto the up/down mount, I have to get RIGHT to the back of the boat. When I do, I bury the transom and water spills in. Thank goodness for the bilge pump!

Now, I have the battery mounted more or less in the middle of the boat. And the fuel tank is built in and mounted forward of center.

My rough guesstimate is that this motor is at least 100 pounds too heavy.
