I sold out

OK so I sold out. I sold my 26 ft Wellcraft. I am not worthy, I do not own a Wellcraft. I figured how to make a cruiser go 50 mph, sell it and buy a new one, LOL.
So.. I sold my old boat and bought a new to me boat and lost $1000 in the process. My new (to me) boat is a pristine condition Thunder Craft with a 3.7 ltr and it goes like stink. With just me in the boat, I can just touch 55 mph. So here is my question, I have a 4 cylinder 3.7. WOT is almost 5k, is my prop wrong. Should I have a steeper pitch and bring down RPM?

55 w a 3.7?..... must be a 10' boat

It's a 17.5 ft 188 hp (488r). I can put the boat on and off the trailer my self. I was going to repower my Wellcraft.. but as I said I sold out. I do not have the skill sets to pull the motor and my friends thought it was to big a job... so here I sit. 55 mph is a little to fast for me but it is nice to have the hammer to drop with the wife in the boat. She gives me $hit every time I do it and it is a blast.
 
those 488's are pretty powerful for a 4 cylinder engine. Search on here about 3.7L engines, they have a few quirks and issues you need to be aware of, beyond that, they work pretty good. What kind of prop are you running? Those engines respond well to large blade surface props like mercury Mirage. I'd try to get it down a little rpm, the valve train doesn't like 5000

I thought the RPM was a little high. It has a spare prop I might try.

LOL, Are you telling me to go away? I thought you guys here would know, as Spareparts showed he did.

No need to go anywhere...why our fearless leader doesn't own a Wellcraft or even any boat...does CTT own a boat?

I'd say you did well, going from an overwhelming project to cruising the lake for a grand....good job.
 
Thanks guys, I knew you would say that. A boat is a boat, once you get bitten by the boat the boat bug that's it. I just wish I was a little closer to you boys. This boat is 17.5 and it's a closed cooling system? I could take it out in salt water. It is from Canada, Ontario and has been here all it life. My last boat was 26 ft and was fresh water, anyway it is a hoot and I love it. I have waited 30 years to own a boat. Today will be my 6th straight day on the water... work gets in the way some times,, LOL :party:
 
Congrats on hitting the water....

BTW certainly not chasing you off but there is another forum that I frequent IBOATS.COM that is also great... much bigger than this one and not focused on one specific boat..... Also a very good chance of finding locals on it.... even up 'thar' in canukville.

Just FYI
 
I bet I can do both. I have heard of Iboats. I do have a logon but for some reason it does not work.
