115 HP Oil Injector system

[spatera]

Hi all, this is my first post and I'm not sure if I'm in the right place. I'm looking at a boat with a 95 Yamaha 115 HP non-injected motor. If I buy it I'd like to find the parts (tank, pump, shaft, lines) and install it on the motor. Are there any out there and if so can it be retro fitted to this motor? I was hoping someone either took one off or had the parts on a bad motor. The motor is a 95 C115TLRT. Thanks in advance, Steve

way way more trouble than its worth.at a minimum if the crankshafts are the same you will have to remove the crank to install the oil pump drive gear.

i will have to agree on that it is to much trouble

Thanks for the input. Not what I wanted to hear but I did ask. I was hoping the drive gear was on all cranks and just had the block off plate over it. Coming from the jet ski side of water sports I've rebuilt my share of two stroke motors and was hoping this would be an easy mod. Thanks again.

I know what you mean. I also disabled the oil pumps, plugged the lines and premixed my jet skis after pump failures and seizures. I just thought the boat motor set ups were more reliable. It's a lot less hassle to mix 10-12 gallons for the skis than 25 gal's for the boat doing it 5 gal's at a time. What mixing ratios do you guy's run your boats? Are you at 32 or 40 to 1? I used a synthetic @ 50-1 in the ski's with no problems but probably won't be using synthetic on this motor unless it's recommended.
