Re: 1999 OUTRAGE 17 Yamaha 150-HP Re-Power

Water temperature was 37 deg and air temp was in the 40's. Just me and my son aboard. We were able to boat a few coho and brown trout to get the season started!

Re: Fuel Tank Vents Before Full

This problem continues to baffle me. I've done a little more investigation. Below are the details. ⋅ I was incorrect about the age of the tank. The fuel tank is original and was manufactured in September 1998. The model number is FMT-54A-BW and it holds 54 gallons. (That is slightly differ...

Re: 1999 Outrage 17 Yamaha 150-HP Re-Power

Jim, thank you very much. I just got off the phone with Ken. He recommended a 17-pitch propeller [but unfortunately no other specifics mentioned here], which is right in line with the calculations shown above. As you mentioned, he is also willing to swap propellers for $40 which seems very reasonable.

The previous propeller was aluminum, and I was not able to find a marking on it before I included it with the engine sale. I wanted t...

1999 OUTRAGE 17 Yamaha 150-HP Re-Power

I am re-powering my 1999 OUTRAGE 17 with a 2022 Yamaha F150XB engine from the original Mercury OptiMax 150-HP engine. I have estimated the propeller pitch as follows: Using the Crouch's Calculator, I got a top speed of 42.4MPH using these inputs: HP = 150 LBS = 2700 Hull Factor = 180 The weight is e...

Fuel Tank Vents Before Full

Q1: what could cause a fuel tank to vent gasoline from the vent hose before the tank is actually full? BACKSTORY My 1999 OUTRAGE 17 [II] is in pristine condition. I am not the original owner. I believe the fuel tank was replaced by a previous owner. The fuel tank is made from a gray metal. The caulk...
