My 1700 Fisherman Lund has a 115 HP Evinrude and I'm stuck at 37mph with a stock 19pitch prop. Would raising the motor an inch and switching to a Vengeance 18pitch help me get closer to 45mph? Need all your sound advice since this boat sees both fishing holes and open water sprints.

you need to check your current WOT RPM first. Raising the motor is worth a try, but prop choice depends on those RPMs. Don't expect miracles, but I'm sure it could get you closer!
 
Raising the motor and switching to an 18-pitch Vengeance prop should help with speed and handling, but hitting 45mph might be tough with that setup

First step is always checking your current WOT RPM. Raising the motor's a solid move, but the right prop is all about those numbers. Don't expect a land speed record, but you can definitely gain some ground!
 
Good advice all around! First off, you should definitely check your wide-open throttle (WOT) RPM. If you think about raising the motor and switching to an 18-pitch Vengeance prop, it might improve your holeshot and potentially give you a bit of extra speed, but getting to 45 miles per hour could still be a challenge with that setup. What's your WOT RPM looking like right now?
 
Okay, 1st things 1st, I get it now from all the great replies. I don't have the WOT RPM number at the moment but any changes would be a shot in the dark without it. I appreciate everyone making sure I approach this the right way. I'll report back once I have had a chance to get the boat on the water for a test run.
 
Smart move holding off until you get those RPMs. Once you know where you're sitting at WOT, dialing in the setup gets a whole lot easier. Keep us posted after the test run!
 
Definitely wait on the WOT RPM before swapping anything. The moment you have the number with you, it's just imperative you'll have a clearer idea if raising the motor and changing the prop would help you. Agree with @pajero do keep us posted.
