My new 5.85m osprey - Photos as promised

bingomike · 05 March 2010, 21:21

Now the rain has left, we were able to get on with taking the engine off and puting the new one on.. Started right away, just got to run it in!!

Attached couple of pics, its not rain water but the spring tides coming right into the yard! slowed work down a bit!

Have put gps arial on and new VHF arial and run cables for transponder. Just got to cut out console for VHF and mount the Garmin.. Hopefully going to get out and start running in the new engine Monday/Tuesday.

Can anyone identify which variant my Osprey is??

Looks like a Viper which originally had twins.

It will be underpowered with a 90. Even the 5.25 needed a 100hp for decent performance.

Hi Dm,

Yes it originally had twins, I used the boat a few times with a 90 4 stroke on the back and seemed to go pretty quick. My theory being the new 90 is a lot lighter so should be even quicker? Also could not afford/justify spending the extra cash on the 110hp i had my eye on!!

What makes it a Viper, still trying to get my head round identifying different makes..

Thanks

Mike

More volume in the bow than the Vipermax and less sharper lines. Not as fast as a Vipermax but you won't find a better following sea boat. Virtually impossible to stuff.

Planes easily due to the warp in the hull, very stable and grips well in turns. Memory is fading now but I think the 5.85 was rated to 150hp.

As with most ribs, better with twins

Opsrey still have the moulds but because of the amount of royalties required, none are built now. Same with the Lynx and Falcon.

It's a shame because the Falcon which is a commercial build would give any Redbay a run for its money.

Perhaps, but with Willko heading up RB marketing, it wouldn't stand a chance.

Sorry but I disagree.

The only way Redbays can keep their nose up is with trim tabs or half a ton of spuds in the stern.

Who's Willko?

He's Willk, like Willko but without the "o" stuck on the end for good measure, search redbay, potatos, dead cows and helicopters and I'm sure his name will pop up......

How rude!

Based on my experience of a 5.25 with a 90 on the back I reckon that 90 Twatsooo will give you about 35 knots at full chat. I would suggest a 17" pitch prop will be best suited.

How does that work then

Kernow Buoy · 06 March 2010, 10:07

Mike my 5.85 Ribtec with an elderly 90 Yamaha would pull 30 kts. She had a 17" pitch prop which was holding her back to about 4500rpm so with a 15" I would have expected 33-34 kts, much older engine that your Tohatsu mind.

Different Hull too, the Osprey would probably be a little faster due to the hull design.

Frankly, "i recummend a kwinkwari"

It has come with 17 prop, the old engine had a 19 stainless and it flew along with that about 40knts with some room on revs still.

I will be happy (at the moment anyway) to be getting 40. Still getting the hang of ribs, my cruiser pushed 27/30knts at a push...

Have chosen to keep the osprey over the humber (going on sale soon) as it has a really good beam, and the new (extra) pod seat i have had made will fit better - still giving plety of deck space to get round.

Using this set up as stepping stone to getting newer hull in the next couple of years...(wife and finances allowing) Lol

Yes mate it's a typo, went to hit the OSPREY key but hit the RIBTEC one instead!

No, just a bit of similarish size/engine comparison for mike's info.

I reckon a Ribtec 585 would be faster than a Viper of the same length. The Ribtecs are fast boats, eh Kernow?

Oh don't go winding Mollers up, he's stiil sore about my old carbed 90 trashing his 150 opti.
