MK 40lb variable speed prob

ive got a transom mount mk that has a dead spot at my favorite trolling speed 25%, seems anything faster is fine.. any ideas on what it might be, and how difficult of a fix... can get parts from motortech in suffolk but working on a budget so would rather not pay for labor..

It's most likely the speed coil. Pretty easy to replae and Tom probably carries them. Here is MK's service manual. http://tnhatlfs01.thenethouse.com/st...r%20Manual.pdf

thanks BB, ill call tom in the morning. that pdf has some really helpful info
