My 15 ft. aluminum v-hull does 22 mph with a light load in it. More weight = less speed.

It really depends on how big your boat is and how fast you want to go typically you want to go 20-25 while tubing so get a big enough motor to push your boat with a tube 20-25 mph
No never keep it locked the lock is for revers only if u run it locked an hit a stump or something ur looking at damiging the boat or motor
This all depends on the boat in which it goes. A 25 HP outboard motor, on a 14' aluminum runabout can cruise at 20-25 mph. Now, if you were to install hydrofoils (do a Google search) to the bow and transom area of the same boat, you could go upwards of 45 MPH +. Although not very common today, hydrofoils are currently used on Italian, and American navy battleships...crazy fast
1966 20 hp.
30cc is equilent to 20 mph
Speed is dependant on a number of factors. Most importantly the size, type and weight of the boat that it is on and the number of people on board. A 50 HP outboard will push a small aluminum fishing boat a lot fast than it will a 20 ft fiberglass boat. I have a 50 HP 2 stroke that will push a 16 foot aluminum boat 35 MPH.
the 20hp Mercury outboard motor runs at the most at 8mph on a good 14ft to 16ft aluminum boat. Mercury.co
I have been looking at rc boats and i saw one that go's up to 20 miles an hour but i didnt know if that was a fast electric boat.
A model TD 20, is a 5 hp Johnson outboard, manufactured between 1946 and 1949.
A 50 HP Johnson on a 20' Lowe Suncruiser goes 18 MPH max. That is at 5000 RPM, the trim at its maximum potential position and a whole lot of gas.
