Yam or Mariner on a 4m rib?

If money was no object and you were kitting out a 4m rib with a new 50hp 4 stroke EFI, would you go for a Mariner or Yamaha engine?

I ask because I'm looking at buying a used boat, and the owner suggests that Mariner (as fitted) is preferable, and that's reflected in the asking price.

I've always assumed Yamaha to be the best, as reflected in the new cost (around 1k more). But maybe he's right, and more users prefer Mariner, not just because they're cheaper?

Look at the local commercial boats and most if not all run either Yam or Honda. I'venever heard of a major problems with any of thier EFI engines in the 40-60hp range

I think they win due to their endless related engine experiance in all the other stuff they make - cars, bikes, quads, snow mobiles, jetski, generators etc etc

I am not sure the smaller Mercury/ Mariner engines of this sort of age 2006 ish were as 'clever' as the Yams or had the same sort of build /reliability. Having said that my 50 Yam is not the most slimline of engines at a hefty 115kg ! Not sure how the others compare to this ? If its to go on a 4m Adventure it may be a weight question between the merc & yam - lighter is defo better.

I'm in no way against Merc/mariner having had a couple and used others & been impressed , but these were the bigger HPs.

This is all just my opinion based nothing more than what I see about and personal experiance. As always I'm happy to be shot down and proved wrong....

OH and if I had choice now I'd probably go 40 etec .!.....

There is a chance they might be one & the same lump with a paint job......

Mariners have traditionally (since the 70s at any rate) been resprayed Yams or Mercs. I forget when things moved around, but the late 70s / early 80s 50-ish HP Mariners were Yams.....

What's best for you might boil down to the local (or not) dealer(s).

If its one of the 2 on B&O I'd suggest the more expensive one is over priced by maybe 750 - 1000 (considering it seems a fairly basic fit) . The other is more realistic ( but is an older boat).

Thanks - it's the 7500 one, in nice condition with the basic Outhill console with side seat and Mariner 50. My feeling is that it's priced for a Yam - hence my question about Yams / Mariners.

Yamaha seem to be the top end of the market and probably make the best engines, they certainly make a boat more desirable and they sell more quickly.

For some reason, as said, commercial users tend to go Yamaha but on race boats you see more Mercs. I run a Mercury 115 and I'm completely happy with it and it's a lot lighter than the same size Yamaha.


7,500 is far too much, look what an extra 2k will get you.....

http://www.ebay.co.uk/itm/6-6-mtr-RI...#ht_500wt_1413

...or 6,750 for this http://www.boatshop24.co.uk/YXZvbis0...ailer.html#top

and another, but not sure if it still available - http://www.boatshop24.co.uk/ZndvMzE1...DVENTURER.html

Even with a 50 Yam I'd still say its 750 + too much. Points of note I'd be pointing out to negotiate over : - no Aframe / lights/ No fixed radio , or plotter. I guess basic gauges - just revs ? When you could get revs , speed , depth etc . Has it got ski eyes fitted already ? Does it have a bilge pump of any kind as it will fill with water if you are skiing etc which is easier to get out by flicking a switch.

Is it rigged with cables on or beneath the deck - no biggy but neater below deck.

When was the battery fitted ? If its the original 2006 one I doubt it will last much longer and wil need changing in the next year ot two at a guess

It is as you say the basic outhill console . While I have never had a problem with them as they are designed for light leaisure use ( same as the boat) they are not overly 'solid'. The console with a screen and stainless surround make a much more usefull set up with more to hold on to when moving about the boat.

And while not a biggy the overall cover is useful , but to get the smaller ones for seats and console is handy as you can tow with them on and easier to put on if you ever leave the boat on the water etc .

Hope this helps , but feel free to PM me ...

Pete

6.6 mtr RIB Boat .Yamaha 115 HP 4 Stroke Engine Including Braked Trailer | eBay

...or 6,750 for this 2006 Avon Adventure 400 Yamaha F50 Trailer For Sale - GBP 6,750 - Lymington, UK - Boatshop24.co.uk

Hmm not sure I fancy a boat made by BABU........and the price for the Avons is just what market will support - very hard to compare them purely on price.

If you need to get it in a garage 6.6 is a looong garage ! Think that boats a classic example of outhil lbeing very unsuitable --- they will break in a decent 6.6m hull when it gets rough. ( but then again so may the hull of unknown make?)

Race boys i think like the fact that the merc race engines are 2 strokes ( XR) unless you get to Verado time. I loved my Opti & also the verados

I'm not saying you cant get a bigger boat for not much more money - they just are into a differing class/use/ cost etc.

I was trying to highlight the fact that 7,5k starts to take you to a different league.

Absolutely ! there are some great boats about for 8k .

I wish I still had a mooring and space etc etc to have one again. I think they price differance starts to show the increased cost of owner ship of a 'bigger' boat - they just cost more to run and maintain/keep than the boats up to say 5m ish long.

Give me six months and I'll be on here saying I've just bought another 7m RIB ( hopefully ! ) - never have too many boats !
