Hey Everybody! I'm back! Its 77 degrees here today so I spent the day on the water. At 8 am the Ohio river was perfectly flat, some leaves and limbs floating but not bad. My rig is still the way I described previously, but I spent today playing with trim and top speed.The boat was loaded with...

AFA marine has some from time to time. You can google small used outboards and find them. Hank

I have not seen a 35 carb. I do have a 30 carb and inlet and outlet side are 1 1/2 in. in dia. However inside the carb throat is a small ridge cast in the body which necks it to 1 3/8. This ridge is 1/8 in width and is centered on the fuel inlet tube. Hank

Very true on volume. I've found a 35 johnson on a boat that hasn't seen the water in 18 yrs. Birds are nesting under the engine cover. I'm trying to bring this home but, I'm watching the computer sources too. I've probably achieved all that can be realized with this setup, the carb is a 30 and...

The intake material is very soft. I used a round file to remove all the bulk and then a Dremel with a sanding drum to finish it out. Took about a half hr. I used long slow strokes with the file as the intake is pretty thin. I'm at the beach right now with my family and we are having a blast with...

I think I'll rig a tach and see what my rpm is . If I had to guess right now I;d say around 4800-5200. Just an educated ear guess tho. Hank

Thanks for the reply! I did the worksheet for the proper pitch prop[ say that three times real fast] and it says a 10.5 x 11 is optimum. I think since this seems to work so well right now I might leave it alone and pick up a 10.5 x 11 for a spare and future testing. Thanks again.!

Alright , time for an update. I've opened up the intake and cleaned the carb really well. It truly is a 30 hp carb. The prop is a 10 x 15. The boat is loaded with the outboard, a 6 gallon metal can , grp 29 trolling batt, Evinrude 3hp Yachtwin for backup, 2 gallon can of spare gas, small...

Test run after dark with the engine cover off. If you have any spark leak[ short] you will see it. Just don't touch it! Hank PS. This will only show external shorts, you cant see it if its internal. :(

Alright, time for an update. I have the new boat home and have the motor in the shop. Carb # is K0432703, ? and the bore in the carb is 1 1/2 in. However it truly is the 20 intake. The hole in the intake is the keyhole shape and I'll bet its only 3/4 at the most. I'm gonna open that up to match...

Hi all. I bought a pig in a poke, motor looks like new , supposedly only used about 20 hours. I'm buying a new boat, a G3 1648 welded hull and I bought this motor to use on it. I took the motor to my local shop to have it looked over. I've been a mechanic for 40 years, so it didn't scare me to...
