Just what I thought.

1 boat - okay, but that's it
2 boats - where am I supposed to park the bl**dy car?
3 boats - your dinner's in the dog (again)
4 boats - someone from the council called to see if you were trading?
5 boats - someone from the Royal Navy called...
6 boats - see you in court!

I'd be very interested to know the exact spec - my SR4 only managed 37 knots with a Yamaha 50.

If there's a 50 that will give me 48 knots I want one for the current 4M

We ve had 48kts out of my ribtec 6.5 with a 175 opti.

That was a gps 48kts on a perfect flat calm day. 3 on board and 2 lots of diving kit. One of those pieces of kit was a Sentinel rebreather which weighs about the same as the trailer!!

I reckon 48 is feasible with a 50hp on a 4m, we've had similar speeds with our Valiant 4.5, 50hp 4 stroke with flat conditions running north of Port Solent


Seriously though, not had the RIBTEC/115 Merc out on a flat day but the GPS shows a top speed of 36.5 knots, my quickest is 34 so far.

Well my SR4 with a 50hp 2st Yamie on will do 33 knots on a good day 2 up!!

I do have Dolphin fitted, one of these days I should remove them & see if I can an extra 15 Knots out of her

You might have to "Supersize" that 50hp...
