Thanks for the advice on the prop. While my setup is fine for myself, it kinda stinks when I have my daughters in the boat, which is almost every time. I am almost never alone when fishing. Why have kids if you don't want built in fishing buddies? :)

I actually did that as soon as I got off the lake. They look pretty good. No flooding, no lean condition. Just a nice tan patina. I put new plugs in before I changed the carb, just to see if there was a problem. I'll probably head out tonight and do some Walleye trolling. I live between...

Agreed. The carburetor upgrade corrected the issue, completely. I may have to up the pitch of the prop at this point by 1/2" or so. It over-revs slightly now, so I just throttle down a bit.

2002 Mercury 9.9HP 4 Stroke to 15HP Carb Conversion I'm posting this, because I've never seen an adequate response on the Internet, and figure people may find it in a search. OK, so, I replaced the carburetor with a 15 HP. I ordered it from readysetboat, and received it quickly. I...

Ok, so today, I took the boat out alone. The engine ran 4750 at WOT, which translates to about 16.5mph, on the gps. I’m still going to change the prop, but may also buy the 15hp carb and exhaust port, since in 2003, the 8, 9.9 and 15 Mercs were all 323 cc engines. I’ll probably change out the...

Thanks for the reply. I went through all of the settings. Nothing really looked right. Finally, I removed a couple of the wraps around the plug wire, and it worked correctly. The instructions called for 6 wraps. It needed to be 4. Now, onto propeller selection. I figure a 7" pitch prop...

Hello everyone! I have a 2003 Mercury 9.9 4 stroke motor on my 1648 Lowe Big-Jon. I am trying to get everything set up correctly, and am using a Searon tach. I set it to the pattern that "looked" right, at idle. So, at idle, the boat moves a little too fast to troll (it has the stock 9"...

I have a Tohatsu 40hp Longshaft. It's mounted to the boat (A lowe 1648) with a tall aluminum plate, to bring the prop to the correct elevation. This doesn't sit right with me, since it acts as a lever, and puts too much torque on the transom. Do I just need to find a proper motor, or can I...

Hello everyone. I'm not sure if I've ever posted before, but do a lot more reading than writing. So, here's where I am, and my questions: I have a 1984 Lowe 1648 Big John. I bought it a year ago, and just got around to removing all of the 2X4s and waterlogged 3/4" plywood decking. The...

I thought about that, but it would have been too spongy. I ended up buying a couple of brass plumbing fittings with close to 1/2” ID, and drilled them out to the right size, then JB Welding them into the sockets. They are pretty much a perfect fit both ID and OD now so we’ll see. I don’t like...

Howdy all! I’ve been reading this forum for a bit, and have a question. I have a 1985 Lowe Big Jon 1648, and will be doing some river fishing in some of Missouri’s freestone streams. So, I took on the task of making a set of 9’ oars, and setting the boat up for that job. I’ve got 1/2” shaft...
