Good Afternoon,
I have a 20 foot welded aluminum workboat with a 115 yamaha 2 stroke. 20 inch. Model number 115 TLRX I need to convert to a long shaft as the waves come in over the back. I have purchased aluminum lift bracket to raise the motor up and we will add aluminum plate to it to block waves.
I also have a 130 hp yamaha 25 inch shaft. Model number 130 TXRY
My questions are.
1. Should I swap the lower sections of the motors around making the 115 a 25" shaft or should I switch the complete motor to a 130 hp which is now a 25" shaft.?
I dont need the extra power and done want to burn more fuel. Is it possible to switch the 115 hp carbs to the 130 ? Is the gear ratio the same?
All thoughts and advice are welcome.
I have owned the 115 for years and has been a very good motor. I bought the 130 from a local who said they had always maintained at the dealer and it ran well. They just wanted to go to a 4 stroke.
