Ocean Rib second hand

Evening all,
I'm thinking about buying a used Ocean rib, 5.9m. It's very difficult to find out anything about them on the net! Been looking for suitable outboards, and have found a few 150Hp Optimax's about at a good price.

1. Any differences between Mercury and Mariner?

2. Any comments on putting this engine on such a boat?

From the links on another thread to a 150Hp test, the optimax seems to be almost as good as 4 strokes except at WOT when it loses out.

Another option would be to buy an old 2stroke and use the money I save for fuel! For instance, Bembridge are selling a 150Hp johnson 1989 for 1600. That's a lot of petrol although that particular engine is maybe a bit too old.

Any comments welcome! Also, can anyone put a value on a 5.9m 1994 Ocean rib, say with an almost new optimax 150. Can't find any for sale to figure out what to offer for it!

Many thanks,

Don't buy the 89 Johnson. It'll be an old VRO which is Very Very thirsty!
No difference between Mariner or Mercs. 150 Opti is good engine but IMHO a bit much on a 5.9m boat. Mebbe a 135 instead? Value of RIB depends on condition & whether it has a decent trailer. If it is OK then mebbe 5k tops ex engine. Say 12k with a new Opti.

WOT = wide open throttle (ie. full power).

Found it!

It looks to me like the optimax is almost as good at cruising speeds as the four strokes, only loses out when run flat out. Do you agree with this?

Thanks for reminding me how thirsty my engine is. 1600 also appears over the top.

On the plus side, its simple, with very few electronics to go wrong, huge carbs to fiddle with, easy to service, and bullet proof. Also sounds fantastic.
