    " For Sale" 1990 Convincor GTX 251 near Jax, FL

    I just posted my Convincor for sale. It's a good boat but my kids have too many other hobbies so she sits in the garage far too long. Make me a good offer and give it a good home. http://jacksonville.craigslist.org/boa/4856593119.html If you have any questions or want additional pictures...

    HOW FAST IS YOUR CHECKMATE? EVERYONE!

    I'm bored at work so I'll chime in; My '90 GTX 251 runs 66MPH with a 3-blade 25P prop at ~4,700 RPM. I have a pretty decent 518ci engine with Gil exhaust but I overheated and cracked one of my 088 heads last spring and I've been running a set of stock peanut port Merc heads I had in the garage...

    How much water in the bilge?

    Just a general question. I hope this is the correct forum. I took my 1990 Convincor out yesterday and ran pretty hard for ~30 miles. When I got back and pulled the drain plug I got probably 5 gallons out of the bilge. I didn't measure but it seemed more than usual. I've taken it out at times and...

    Jacksonville Checkmates?

    I spoke with a friend of mine last week in Callahan that has a '90 Convincor and he said he would like to go sometime but probably later this summer. I have no plans so post when you think you have your boat ready and we'll plan something. Speaking of, how is you boat coming along? I took my...

    Jacksonville Checkmates?

    Hey guys. Any interest in meeting up at the Landing or Six Mile Creek or anywhere else this summer? I know there are few old Convincors like mine in the area but I never see you guys out on the water. Let me know if want to meet up some time.

    " For Sale" 1990 Convincor GTX 251 (Jacksonville, FL)

    It saddens me but it's time to sell my boat. This is the listing. http://jacksonville.craigslist.org/boa/4400761727.html I have lots of other information I can send on request. It isn't perfect but it's been a good boat when we've used it. Unfortunately it just sits in the driveway and garage...

    I pulled everything apart and went to the local bearing supply house and got my bearings and a new seal. I splurged and got SKF bearings instead of the Chinese knock-offs and it was still less than $25 out the door for everything. It took me a couple of hours to get the pump back together and...

    Now that you've brought that up, all of your previous plumbing comments make a lot more sense. With the OEM style pump you have in the picture of your engine the cooling water route would make a lot more sense instead of wrapping around the engine like mine does. I didn't notice before that...

    I got to take my boat out Sunday afternoon. It was high 70's and sunny all day Saturday while I was working and then cold (50's) and windy Sunday afternoon when I went out. The oil cooler worked really well. The temps came up to ~160 while I was idling and cruising out into the river. When I was...

    That's the major drawback up buying a used anything. You have to sort out what the previous owner did. In my case the boat ran great and has over 100 hours on the engine so the way the cooling and fuel systems are plumbed obviously worked, but it makes me scratch my head. Why someone would spend...

    I debated hose over tubing in my head for a long time. When I bought the boat it was piped from the inlet hose to the raw water pump with PVC and an automotive hose and from the raw water pump outlet to the crossover inlet with an automotive hose. I've had failures with automotive hoses (on...

    Help me identify a couple of things...

    I agree 100% and intend to do that this weekend once I'm sure I've got everything mounted and installed like I want it. That was the first thing that jumped out when I first looked at the boat was that he used regular automotive hoses and single clamps on everything including the exhaust hoses...

    Help me identify a couple of things...

    Well it's been a while but I'm back on my project. We took the boat out a couple of times in the past month and it's been running great. Even without a cooler the oil temps were running right at 240 degrees if I keep the speed at ~30MPH. We made a 60 mile trip two weekends ago without issue...

    Good morning guys. Definitly no coolers installed on my engine. It is a Gen VI engine with a remote filter adapter on the block and a remote HP-4 filter. Like you said about your engine, the people that built the engine did a fanstastic job and used all the right parts but I don't think they...

    If you don't have them availble don't sweat it. I'll order up a cooler next week after Christmas, so my wife doesn't shoot me, and spend a couple of evenings staring at it until I find what looks the best to me. Not too many warm days left so I'm anxious to go back out before cold weather sets...
