No, the prop is the same that was on it before rebuild... but the boat has never gotten decent speed or hole shot since I've owned it. With just myself in it I might get 36mph or so... unsure about the RPMs with just myself.
Would making the prop diameter give me more RPM's as well or should I...
The motor is in excellent condition, it was 100% rebuilt a few years ago and has less than 20 hrs on it since rebuild. There were 3 guys in the boat so we were weighted down I suppose, plus live well water.
I've never been happy with the hole shot or top speed at WOT with this old boat being pushed by an even older Tower of Power Mercury. Here's what I've got:

About 4 years ago I had my Merc totally rebuilt by a man in Milwaukee who works for Mercury. He specializes in the old Mercs and he did an incredible job! Every nut and bolt was taken off, the entire motor was went through right down to having it...

I’m on vacation and last evening I noticed my water stream coming out of the tell tale was just a trickle. I proved around hoping there was a clog but no luck so now I’m trying to do an impeller replace at the lake. I’m praying to...

Need some help here... I'm leaving to fish Norfork and Bull Shoals down in Arkansas in a few weeks. Since it's been 5-6 years since I've had my boat down there from my home in Indiana I thought I would check the Arkansas regs to...

So I pulled the lower unit to replace the impeller, which was easy enough. Now I'm 6+ hours into trying to get the drive shaft to seat properly into the motor while at the same time getting the water tube into the pump housing. I've got the motor...

I acquired this motor with zero information about it's history, other than it ran. I can get it to start up on starting fluid, but then it's the same story... it dies. I pulled all fuel lines and rinsed the tank. There was a...

I was at the lake, all was well until......... the starter solenoid seemed to crap out while on the water around midnight after a night of fishing. The solenoid would just click rapidly so we knew it was toast. In desperation I jumped across the...
Santa was nice enough to bring me a Lowrance Elite 5 w/ Chirp with the 83/200 transducer finder for my boat. I currently have a Lowrance X96 200 kHz finder on the boat. My question is can I run both finders at the same time without experiencing too much interference? Both transducers are...

This past weekend my old Tower of Power developed a situation where it would seem to flood and die when I attempted to throttle up beyond idle. I could get up to about 1200 RPM, and then as I continued to push down it would just...

I just got all my carbs pulled and I'm about to begin cleaning and rebuilding them. Can someone tell me what's the deal with these two screws that have the red paint on them? Is that locktite? Should I remove them to...
I just purchased a Marine Grade stereo system for my boat. It's your standard 12-volt setup with 2 speakers. Due to space constraints I had to mount the stereo on the port side above the glove compartment. What I was hoping to do is run my wiring from my trolling batteries so I don't drain my...

I'm wanting to do a total Carb Rebuild but I'm having a hard time figuring out what Carbs I have. I see on the top of the Float Bowl Cover it has the number 1395-5677. On the bottom of the Bowl Cover it says Mercarb and has a...
