New 1996 4 hp Johnson Seahorse

I am new to the forum. I have a new 1996 Seahorse 4 hp. I don't mean new to me I mean this motor has never been on a boat until I got it. I got it from my uncle that got it new for a trolling motor and never put it on.
I mixed up some gas 25-1 like the books say for a new motor. I ran it in a barrel for the first hour of break in. Then I put it on my inflatable pontoon and took it for a two hour run. I am breaking it in by the book. I have ran it up to full speed a few times and it runs good. Here is the question.

I have a 2.6 hp Coleman 4 stroke. It will push my boat at 5.1 mph. The most the Seahorse 4 hp would push it is only 6.1 mph. Is that all the faster it is going to run? I do have a video of it on the boat running if anyone thinks that would help. Here is what the boat looks like. Thanks. Ron

Most likely correct, it does not quite look like a speedy one? In your case more likely a question of 'hull speed' as maximum obtainable.
