Hi all,

I have a 2005 Yamaha SX230 that is in need of a wire harness - part # 99999-03770-00. I have put a lot of money into this boat and now cannot find this part anywhere. Any ideas, suggestions or help would be greatly appreciated!

thanks!
 
What harness is it? I have an 08 parts boat, maybe it would work?
 
I believe it is the Engine Wire Harness [HASH=108]#1,[/HASH] but I am confirming with the dealer now.
 
Do you have the HO motors or the 140hp motors?
 
I do not have the HO.
 
Original issue was a rock stuck which didn’t allow the engine to turnover. Did not see it until the boat was out of the water.

The Yamaha repair shop indicates there is a short in the wire, sometimes causing the motor to not spark each time. When it does start, engine runs fine.

Completely different part numbers. The 05.

It is the same harness as used in the 06 and this and my and @Scottintexas 's Orange 07. it changes in 08.

I do not know the difference between 07 and 08 as they are the same engines.
