I have a crown line 4.3 mercruiser. My boat won't go more than 10 mph and never plane off. Starts great doesn't miss at all. Just won't get to top speed or anywhere close. Has new plug wires and all. Any comments would be helpful.

Also seems to hit full power in reverse at about 5000 rpm or higher. Maybe carburetor ??

Never sat in water. It is backfiring a little bit. Warm up is around 5000 rpm but in forward only hits around 3000 wide open. Plug wires are new. Starts no problem and is running great not missing at all but still not going any speed.
Thank you!Ill will post what the problem was when I know.
Did you ever find out what’s wrong. I have searched and searched and I am having the same problem with no answers. I’m lost.
