Mariner 150 Opti-max

[Nick Hearne]

Hi, I have been looking out for one of these for some time at a good price, to put on Rosie!
This one http://cgi.ebay.co.uk/ws/eBayISAPI.d...MEWA%3AIT&rd=1
is 6 years old but ony 70 hours, looking like new!

Did they not have problem with these in the early models?

How much do you think fitting buy a dealer will be?

Is Opti oil that expensive?

Any one got some ideas to tell the wife as to why we need it?

What do you think the old 1992 Johnson 100HP be worth?

Any good or bad thoughts to this sensible idea?

Wouldnt 150hp be a bit much for a 5.75m RIB?

Early Opti problems I think were more on the 200hp's. On a 2001 Merc Opti we had a problem with the trim pump but that was it. Dealer fitting I guess around 500 quid. No idea on price of Opti oil now.

I would guess your current engine is worth what 1000 quid? Assuming in good nick.

Ebay seller looks to be a bricks and mortar business so thats reassuring. (IIRC there is an outboard motor shop in Rainham Essex so mebbe the same people.) 6 year old engine with 70 hours? Hmm, mebbe the old adage about more hours = more care is important. I think their reserve price is pretty high for a 6 year old motah.

No idea how to convince your wife. Sorry!

Thanks for that, Viper 5.75 is rated up to 150hp so it should be no probs also it will move some with this on the back! Also I'm hoping to get a improvement in fuel consumption cruise at the 20 to 25 knots mark!

HP looks OK on the RiB but please take care OPTi's are heavier than their 2st Equiv, ensure that the transom can take the weight.Stay Safe.

Nick that is really going to fly with that much power, there will be queues for rides on her. Paid £3.5k for a similar engine a year ago.

50 to 55 knots, that should keep the kid quiet!
Anyone know the difference in weight of the 2 Eugine's?

Nick,

If you get the opti check to see that there is a blue collar around the injectors or the intector is totally blue. If the engine hasn't got this then I'd steer well clear.

Its about £1k to get all the injectors changed and it should have been done under warranty about 3 years ago.

Besides that I'd check to see if OPTI oil has been used or not. Its not the end of the world f it hasn't but it gives you a good indication if it has been looked after.

Its also worth remembering that low hours isn't necessarily a good thing!

Nah way. Try a 5.5 Humber with a 150 Opti. Lots of smiles per mile!

It dose not appear to come with smart gauges, are these going to cost the earth? Aluminum prop not so good ether!
