The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
Hey guys, been a long long while since visiting this site after competing my "project" boat. Got that done with some very good help from a lot of members and do appreciate it . Now for the problem at hand this time. I was doing some tuning up and cleaning on the engine and had the carbs off and...
I have a '77 70 hp Johnson O/B I don't know what prop is on it (in fact have two props and no numbers I can find). But , I want to troll with it and not worried about top end speed as I only fish. What prop would I want to get to get the slowest possible speed? I have turned down the idle but...
This may sound like a noobie question , but honestly I have fished for over 50 years. For a long time I was out of the fishing thing and the last 6 years got back into it . I fish solely and religiously for cats,but lately haveing a hard time finding big ones in the lake I fish. I was wondering...
Re: Got a question on "foam"
ok, I wasn't sure , but thanks for the info. I noticed that there is two different foams in the cans. One for close small fills and another for big fills. I read the descriptions and looked the manuf. on the net all claim to be "closed cell" I don't really know how...
I am in the middle rebuilding a 15 foot trihull "magnum" brand open bow. I have the top off and the hull cleaned with new stringers in now ready to pattern and cut the floor. I was going to order the foam that mix in two parts and pour in the floor for sound and added insulation. I noticed at...
I am in the process of renovating a trihull Magnum 15 footer open bow (not the expensive high speed Magnum ). I am making it a fishing boat for my purpose only. I am down to the point of cutting new stringers and patterning the wood replacement pieces. I have a Garmin Echo 200 fish finder that I...
I am back again with a question on a 1977 Magnum tri hull 15 foot open bow. I am trying to replace the stringers which the floor and stringers are rotten. I was going to replace up to the open bow part but the further I go the worse the wood is. So thinking now I need to do it right . There is a...
This just started yesterday running across the lake. I left the dock and everything was fine. I stopped at a spot and fished for about an hour. Wind came up and I started for the other side of the lake , after a few minutes the motor started to misfire (for lack of a better description) running...
Hey guys , here in Arkansas the temps are going down to 30 at night but warming up to sometimes near 65 and 70 in the afternoon. I was reading and began wondering if I am the only nut case left that is taking the boat out and fishing all day? Water temp on the lake is about 51 degree surface, I...
My boat is a 15 foot trihull with a 70 hp Johnson. Its an old boat , boat/motor/trailer are about a '77 model. Right now it has 5.30x12 tires on a 4x4 bolt/hole pattern. The boat sits high on the trailer and off the ground. With the low water we have now and the short distance (15 miles) I...
I am a avid catfisherman so to speak and usually do fairly well using livers, dough bait and chicken guts. I live in Arkansas and been looking at something in the local Walmart but just skeptical of it. Its from Magic Bait and called chum. Its in a 2 lb. bag and looks like ground bone meal that...
Re: Putting an electric winch on boat trailer. Would like some help
The winch I am using is a 2,000 lb Champion winch off a ATV I had. Remote control , and a button. The tag on the winch just says 2,000 stall load, 120 amps at 2,000 lbs. I am illiterate when it comes to electric stuff . All I...
I have an '03 Ford extended cab with a V6 and the factory towing package. 2 inch receiver, 7 pin flat , round plug, and the standard 4 pin flat plug , all standard factory options. My question is this, I put a 3,000 lb. ATV winch on the trailer making the brackets and all that , then set a car...
This motor is fairly new to me for about 2 months now and a work in progress trying to get it going. Its a 1977 70 hp Johnson . I thought after a new switch and a broken kill wire in the harness to the engine it was doing ok. It has been running fine except its hard to to get going at first...
While the forums was down , I was searching around the net with the usual question. "Whats the ratio fuel oil mixture for a Johnson and how much oil to gas." I have seen this many times posted and asked (including me). I found this neat little web site that has a calculator for oil mixture...
I have a 1977 70 HP Johnson (new to me). When I got it the guy said it started "not shutting off with the key" I posted here for some help and ordered a manual. But, the manual don't help and no answers got the solutions. I put in a new key switch , traced the wireing down and cant find an open...
I have been getting a 1977 70 HP, Johnson ready to put in the water, had trouble with it idleing and fixed that I think. Put in it a tub of water well over the top plate. Now it idles great and excerlates beyond expectations. Now my problem when idleing in the tub I see a stream of water out...
I bought this old boat or traded for it a couple of weeks ago and waiting on the guy to get me papers on it. The motor is a 1977 70 Johnson, seems to run great in the tub. I took it to the lake today to give it a test and see what else it needed while waiting. It started and idled on the first...
