I picked up a c.1990 Guardian 18 hull last year and spent a bit of time putting a few bits on so that i could use it--it has been abused!
I'm using a Mercury or Mariner 150 V6 two-stroke with a LASER II 19-pitch propeller. I've finally got it out on the water and i'm struggling with a few things.
As you apply some throttle from idle, the boat starts to accelerate but then the engine will rev completely disproportionally to the gain in speed (like a car with the clutch worn out). I manage it by reducing the throttle and then re-opening slowly, a process which could happen a few times before you're planing.
I'm also only achieving around 25-nautical-miles-per-hour flat outl was expecting to hit more than 34-nautical-miles-per-hour.
I don't have an RPM tachometer currently.
Any help or advice would be greatly appreciated!
