I am new to iboats but have been getting alot of help by reading other posts but you can only go so far that way. I have a 1963 starcraft 15' with a 1963 Johnson 40 electramatic, that I purchased this year(my first boat). Here is a list of things I have done:
1. replaced the lower unit with one off of a 1963 evinrude
2. new gas tank, fuel line, primer bulb and connections
3. points and condensors gapped to .020
4. replaced gear oil with type c required for electric shift
5. and two new plugs
I am starting to get frustrated cause something happens every time I go out. First it was kicking out of gear while driving, then i got that fixed and when i was testing that the motor died hence the points and condensors. Now after all that I took it out and it idles great, shift into forward and reverse and generally speaking works great with the exception that it only goes forward at less than half speed. I watched the throttle and the butterfly opens all the way when in forward but doesnt go any faster that trolling speed. before it died last week it would get up on plane and cruise quite nice. I just need to know if anybody else has had this problem and how to fix it? I hope that this is enough info to atleast kinda understand what im going through. and here is the motor info:
1963 Johnson 40 horse super quiet electramatic
compression top cylinder 100
bottom 95
model RK-25D
serial 2342985
Thank You,
Nick
