    15HP Johnson runs great on muffs / bogs at the lake

    I appreciate the responses everyone, I took the boat out again today to check for loss of spark. To my surprise, the boat ran flawlessly! This is crazy, it went from being near impossible to run on the lake, to running 19mph (GPS) with a partner, 4 rod and reels, tackle, battery, trolling...

    15HP Johnson runs great on muffs / bogs at the lake

    Well I've got bad news. I got my fuel pump rebuild kit from iboats, and rebuilt it in accordance with leroysramblings website. I checked it by blowing through the inlet port (which allowed air to flow through) and then blowing into the outlet (which did not allow any air to pass). This check...

    Alumacraft MV 1648 NCS

    Welcome to the forum. You've got a nice boat there. Is that a 15hp Coleman? About the flooring, I think a spray in liner would be a good idea, especially because you would be adding a non-slip surface. I wonder if that stuff weighs a considerable amount? It would be easy to clean too, as carpet...

    15HP Johnson runs great on muffs / bogs at the lake

    I went ahead and ordered a fuel pump rebuild kit today from iboats, hopefully it will take care of the problem. I'm also going to inspect the pick up within the tank. As for the thermostat, I just put a new one in it. I'm guessing the water coming from the upper exhaust ports is normal, I...

    15HP Johnson runs great on muffs / bogs at the lake

    I would like to thank everyone for their responses in assisting me with this whole thing. Well I've got some good news. Today I went out and got a large trash can, so I could simulate the back pressure at the lake. After doing making some adjustments to the slow speed needle, I managed to get...

    15HP Johnson runs great on muffs / bogs at the lake

    Thanks for the input everyone, today I'm going to buy a large drum so I can actually run it with the added back pressure of water. I bought the engine just a few miles away, so I'm guessing that it had been set up to run at my current altitude. When I apply the choke to keep it running, its...

    my 1436 build

    I've never seen a transom extension like that before, but I bet that thing flies! You should do a speed check after you finish painting.

    15HP Johnson runs great on muffs / bogs at the lake

    Thanks for your support nccatfisher, I am using fresh gas mixed at 50:1 ratio. I think I'm going to go check all my fuel connections, as my primer bulb does not remain hard while running. It's a little firm, but not as hard as it was when I prime the engine. I suppose I could have air getting...

    15HP Johnson runs great on muffs / bogs at the lake

    When I redid the carb I made sure to clean it as thoroughly as I could. I didn't use water, but instead i used a parts cleaner. I used the evinrude rebuild kit, which came with a new plastic float. Both jets are very clean, and I reassembled with a new bowl gasket. One strange point, after i...

    15HP Johnson runs great on muffs / bogs at the lake

    Any input would be greatly appreciated... I've been working on a 76 Johnson 15hp short shaft, pull start. This engine had been sitting for 3+ years before I got my hands on it. Problem: It will run fine on muffs in my driveway. Starts on first pull, revs, pumps water great from pee...

    Grumman 1438 deck with storage

    Well I finally found out why my o/b was overheating. After a new water pump installation I decided to take off the powerhead, and look at what I discovered. Where the water pickup tube runs up into the exhaust housing there is a huge fracture, and a lot of the surrounding metal is gone. This...

    Added fishfinder mount

    That looks like a great idea! Is that a rode holder next to your finder?

    Grumman 1438 deck with storage

    Got some more work done today. I just need to decide exactly where to cut my storage hatches. This thing makes cutting aluminum so easy! Waiting on a new impeller, carb kit, and thermostat Adding some extra bracing to make this thing as strong as possible. Cardboard first Getting...
