Max mph 150 faststrike

[Tripletcrappie]

I recently purchased a 1991 stratos 274fs with 150 faststrike. No jake plate. My max speed right right is roughly 45 with 21pitxh aluminum prop running around 5700 to 5800 rpms. What prop do you recommend for max speed? Also idle is little rough. Sometimes it will die several times while trying to put into gear. Eventually after several tries it will finally go into gear and run. It runs really good when you have the gas into it. Any tips on helping this. Thanks

Look at your shift cable

Not sure what you RPM's should be for that motor but 5800 sounds very good, it is what my 225 runs at. I picked up several MPH switching to a stainless prop years ago that was the same pitch as the Aluminum one that I had been running. Not sure why your engine dies going into gear. Way to many possibilities. maybe fuel? when it is in gear does it idle good?

What's the idle speed? Check in gear once it stabilizes.

Somethings not right, at 5800 with a 21 in prop should be putting you over 55mph. Is your Tach accurate? How are you measuring the speed, GPS or water pressure gauge?

Speed was not gps verified but will try this weekend. Did notice the prop has couple nicks in it didn’t know if that would affect anything or not. The idle speed sometimes will run real smooth then sometimes have to bump gas little to keep it running. Thought about new prop if think it will help.

Just put new water pressure gauge on it and haven’t had it out to try yet. Also new stator regulator and ingition box. The tach wasn’t working but mechanic fixed when did all the other work.

I was referring to a water pressure speedometer when I said Water Pressure Gauge

Sorry I realized that after I replied. Took out yesterday with the grown men full tank gas and equipment with gps 44mph.
