A planer

35-36, In my DeLuxe with back to back seats, two largish men (90kg) and approx. 30L of fuel in the nose and 10L in the back.

I´m sure the 3 cyl 60HP merc Clamshell in hole 4 on the back helped a bit, but it WILL start to wobble, And it will NOT go away unless you ease off the throttle, and fast too (Don´t ask, but until recently i had not seen a grown man wet himself in fear :-)

The Clamshell is a surprisingly light lump - 83(ish) KG. The 55 shares its leg / gearbox etc with stuff like the 75, so is remarkably lardy, even if it is a bit more torquey.

No surprise there - my old SR4 with a Suz DT25 on the back ran happily with a 12"....... (21 Knots flat out 1 up + 30-ish L of fuel.)

What size of prop did you have on the 55 yam?

What size of prop was on the yam 55?

When I had a yam 55 on the back of mine I ran a 14p prop most of the time, I also had a 13p prop that I used when it was full of family. I ended up selling the 55 for a 50 with ptt but I miss the torque of the 55 and kinda wish I had retro fitted it to the 55[emoji22]
