Greyhound finally takes to the water!

After much fitting out, Greyhound finally took to the water "properly" on Friday morning.

She initially had the lower leg replaced, as there was a crack in the old one, however subsequent use showed that the dog clutch was worn, so she wasn't selecting the gears properly. Never a problem for the mechanic - he stripped out the entire gearbox, and replaced it with the shiny internals from the one with the crack in it.

Having been assured that everything was ok, I launched her Friday morning for a test run, which she performed admirably. She was then working a level 2 course at the weekend.

On Saturday evening, at the end of the course, Rich (laser) and myself took her out for a spin. We wanted to see what sort of speed we could get out of an old 1991 2 Stroke Yamaha 115hp on a Ribtec 585, and although we probably had 2 knots of tide under us, the max speed recorded certainly put a smile on Rich and my faces:

Cheers Paul! No gale force wind, but it was bloody cold, and the lure of a hot chocolate compelled me to shift her that little bit faster...

115hp Cowling on a more powerful engine? Well, you never know... my mechanic just fitted an engine with 90hp on the cowling to his hardboat, apparently it pushes out 150hp as it's a well tuned v6... Stranger things have happened at sea...

Thats quick Jimbo! What was it like at that speed? Those Yamaha v4s are nice smooth engines although a little juicy. Maybe yours is a 130HP!!! You get any action shots?

Believe it or not, it was very composed at that speed. A little wobbly, not really a chine walk, just a little sway side to side.

The yam is a really nice smooth engine at high revs, but it is a little lumpy slow (then again it's a 2 stroke). She's great when she's warm, but she really **really** hates cold starts.

She's pulling just under 6000RPM, I'll have to check what the prop is on her. Pretty sure it's not a 130hp, but hey, with Deans tuning, could be anything....

No action shots as yet (it was getting dark) but will be out for another play soon (Benc has agreed to go for a blast with me in his Rib) so should get some decent shots then.

Cheers!

Our Ribeye 585 and 115 yam 4stroke ,same hull i think, reached 39 kn last year 4up ( and i'm not called ox for nothing)heading back from the Needles to Mudeford.Mind you the sea was like a mirror but if it says it on the screen its good enough for me .
You're making me all jealous stuck up here in the Mids.Roll on global warming then the sea might be on my doorstep

Exellent work Jimbo. Especially after all the hard work you've put into it.

I did the same tests first time I took mine out, peaked at 35kn. When playing around with the gps at home I was amazed to see max speed as 53kn? I couldnt remember going that quick.

Then I remembered I forgot to shut it down before driving home. Doh.

Well done.

ROTFLMAO! Luckily mine is a fixed mount GPS, so no such danger!

Thanks for all your nice comments, it was really good to get the boat running nicely. Ben and I are probably possibly photoshooting tomorrow...

Now all I have to contend with is the problem of my engine possibly running too lean, and possibly needing a new big end... Anybody got any dirt cheap 4 strokes?

Jimbo, great news at last!!!! It's definately a 115hp.

Hey, check the max revs in the manual, I think 5600rpm was the max for that engine. With the prop I gave you on the boat, it never pulled more that 5700rpm. 6000k sounds too high.

The max speed I ever got from her was 48mph and that was some time ago. Not had more than 40mph for years. Then again I carry more weight than you starving students!!!

Also watch the fuel, it will burn it quickly.

I hope she continues to perform
