i changed the motor from one boat to another and now it smokes like crazy and will rev up when it is idling on a water hose

Customer: the 150 optimax ran perfect on one boat I changed it to another boat and used the wiring harness on the boat I changed it to but it looked the same as the other boat and put it in the water when I started it it smoked real bad and it will rev to about 35 hundred rpm on its on

Hello again. I wan not holding off for any money. My computer decided to run an update this morning and then I had baseball practice. We all do this on the side. When you installed the engine, did you shift the engine to forward several times while you had the key on? This would account for the smoke. Or is there oil in the fuel of the boat?Will the engine slow down after the throttle goes up?Do you have a gauge that can read over 120 PSI and can screw onto a fitting like that on a tire?

I did shift the engine forward 5 times I found that info on the you tube for free. I have taken it to a mechanic so don't worry about it anymore your reply was too slow so I asked for a refund on my credit card, even though you do this on the side you should let your customers know, this info was way to slow when someone is working on their boats their self

Ok, good luck on the engine.
