I bought a little boat the otherday with a chrysler 45 on it. Im not sure what year or model im guessing 74-83 it has a whie top with old school chrysler emblem in a brown gold background. Anyways I used it for the first time yesterday and it worked great no complaints plenty of power.

Today I brought it out and used it for about and hour with now porblems as i was coming in i noticed when i had it a little over half throttle to open that every oncce every 10 seconds or so it would experiance a skip or a jump in the drive, not an electrical skip or miss but it would cause the engine to bounce a little. it almost felt like would hit something but that wasnt the case as i was in 50 feet of water. I havent had a chance to tinker with it due to it being dark. However this would not do it when going slow or putting around. Im not a marine expert but would would anyone have some insight to what the problem may be or where i should start trouble shooting. Im not an outboard expert so i have no idea. Any help would be appreciated.

-Thanks Chad

Gas was brand new today, filter is fine... When it does that it doesn't feel or sound like it is starving for fuel...

it surely sounds like the clutch dog, is going out in the lower unit. requires new dog, and atleast forward gear.

This doesn't sound at all like a "discussion not involving trouble or repair."
