Outboard power

Could do with a bit of impartial advice. I'm after a second hand six meter leisure oriented RIB. Something like a Ribeye 600 Playtime and I would like some advice on outboard size. We are a family of six, effectively three adults and three kids. We enjoy estuary trips, blasts out to sea for an hour or two and the odd coast hop. East coast and south west mainly. will also tow ringos very occasionally, usually with three others in the boat.

Not looking to cruise at much more than twenty five knots but I would like reasonable acceleration with the whole family on board, especially out of the hole. Top whack not that important. Our other boat is a Boston Whaler dauntless 180 with a yamaha 150. If any of you can compare performance to that I would appreciate it. That tops out at thirty seven knots regardless of conditions, trim etc.

Seen six metres with nineties up to two hundreds. What are your thoughts????

Thanks

Richard

I have a 225 ETec on my Ribcraft 6.8 but I reckon you'd be fine with a 150hp four stroke. Several manufacturers make lean-burn models that are reliable and fuel efficient.

I'm guessing, to some extent, but I think with a fast hull like the Ribeye, a 140/150 will see similar performance to the Whaler. If you want a bit of oomph, 175 would be ideal. 200 would be OTT.

Look at it this way.

If you go for the biggest available, you can always close the throttle a bit. It's hard to open it up if you think it's underpowered.

Leisure ribs IMO appear to be suffering from a trend of lowering HP on their boats - Ribeye do appear to be one of the principle culprits.

Personally if I was starting out on a 6m rib I would look at 135-150-175hp given the load you're going to have onboard.

At last, a man after my own heart. I always thought I was a lonely little voice out here in the max HP wilderness.

Just a thought........ You may find a 6 meter rib a bit cosy for 3 adults + 3. Not sure what age the 3 others are, but they have a nasty habit of growing up very quickly. Especially if you want to throw a ringing in the boat you may well find yourself short on space very quickly..... ??

Totally agree. Often the more economical route as well, if you can control your throttle hand that is

Yes, for a leisure RIB that is plenty. Would not want to regularly carry that many on my 6.5 metre. Mind, I have had 13 divers on a 6 metre, but there were certain limitations

Hi

Most people who buy engines always end up wanting a bit more and trade up and though it is good for business I would start with a 150hp min. If you can max the hp for the boat even better as you have no speed limits and you will crave the extra power.

Good luck

Thanks guys. How do you deal with insurance when the max rated HP on a ribeye 600 is 120??

only stick 120hp on the back ?

I have dealt with case where although insurers have been 'aware' of the over rated engine they still refuse to pay a claim .....

I'd approach this one the other way around.

Go for a well loaded up test blast in a Ribeye 600 Plaything with a 120hp on it. It'll be a 4 stroke Yammie, like as not. If you like it, go for it.

If you hate it, then you're probably barking up the wrong tree.

I can help

I've just taken in a 2003/4 Ribeye 600 Playtime with Yam 115hp 4 stroke on the back. Your welcome to put some fuel in it for a test drive, load it as you see fit (provided it's within ratings and you bring the necessary life jackets etc). That should help determine what you need.

The one I have is for sale too for stupid money (under £8,000) but there is a story behind why it's so cheap... Which I'm happy to explain if required. Perfectly function able boat though! In fact I'm hoping to use it myself this summer so please don't buy it :wink:

Another option is the Ribeye 785 on Boatshed hamble (i think) with yam 200 Vmax 2 Stroke (no trailer) priced £14,000 - a customer of mine in Ireland told me £11k would buy it - not sure if that's correct though. I think there was one on here too could be the same one.

By ignoring advice on this thread suggesting you put a huge o/b on the back. Buy a 120 four stroke and leave it at that. It's not all about speed: fuel economy, reliability, cost and weight are just as important.

Boatsandoitboards just left you a voice mail. I'm interested to hear the story of the boat you've got for sale.

if it is any help to you I run a Ribcraft 5.85 with a 150 V6 2st on the back. It goes like shite of a shovel ay WOT but I never use all the 'horses' for cruising but it is handy to know its there when I need it for what ever reason.

If you think a Boston Whaler handles in any conditions, you're going to love the way the rib will handle!

They don't have to be mutually exclusive

I've not picked up my voicemails for over a week and won't do so for at leas another week due to a family hospitalisation. I can however access the web (thank god) and have long periods of waiting outside "critical care" so I'm going to send you a PM with further details on this boat. Unfortunately I'm not in a position to do anything work wise right now other than admin or web based but as soon as I can I'd be happy to progress your interest further. The boats not actually up for sale anywhere yet so rest assured, its going nowhere. Your welcome to have first refusal on it until my return to "active duty" though

Pm to follow. Cheers
