Hello
Okay, I know some of you are going to say I am in the wrong forum, but there is a reason why here with the photos that I presented. I know this is for waverunners, but I am trying to figure out what the application the port motor in my boat fits.
I have a 2005 Yamaha AR230 that I purchased used. The Starboard engine is the original motor. The port engine has been replaced with a new short block. After inspecting the starboard engine, I notice the water tube going into the valve cover is located towards the back of the valve cover, between the last 2 spark plugs. The tube comes up out of the valve covergoes straight out and then makes a 90 degree right turn and connects to a rubber hose.
The port engine (left side) has been replaced with a short block. On this engine the water tube is located towards the front of the valve cover, between the 1st 2 spark plugs. The tube comes up out of the valve cover and then turns a 45 degree, totally different from the other engine. With the tube in this position it will not let me install the air filter in the correct position.
If I am not mistaken all Yamaha SX & AR 230s engines are designed like the starboard engine, with the water pipe towards the rear of the valve cover. I am just wondering if the port engine is from a waverunner because of the location of the water tube. Can anyone tell me by looking at the photos and the location of the water tube what the application of the motor is?
Maybe its out of a motorcycle since the engines are used in the YZ bikes.
I would appreciate any help.
