Opti vs 4strokes

Can anyone tell me how economical the Optimax engines are compared to four strokes, in the 130hp region.

Any comments on Optimax vs Four strokes gatefully recieved. I presume servicing on an Optimax is considerably cheaper?

Thanks

Rodger Webb

I've seen my mate's opti service bill, and it wasn't cheap (he did take it to Dave Crawford tho') Look at Andy Clark's web site www.bosunsmate.co.uk I think he charges extra for Optis because of the DDT (look on his site for explanation of the acronym).

Also with a 2-stroke you've got the 2-stroke oil to pay for. 4 per litre. I'm using about 4 litres every weekend at the mo.

What size boat are you getting? Don't decide on the engine until that's sorted, or at least decided, so you can match the two. For example, many people are posting good reports of the Suzuki DF140 four stroke on 5.85m to 6.3m RIBs. (thinking here of mstacey and alex brown).

Thanks for the reply, I am buying a Ribcraft 5.85 in the New Year and had more or less decided on a Suziki helped by earlier posts, but was starting to reconsider having read posts on the Optimax. I think I will stick with my original choice.

Sounds sensible. I don't know if there's an opti between 115 and 150, and the 150 although it's a great engine by all accounts, it's a very heavy lump - it's a 2.5 V6 and almost as heavy as the 225 if I remember correctly.

There is a 135 Opti but it is dearer than the Suziki 140.

Got to go now - off for two day rib training course at Salcombe - do you think I'll need waterproofs!!!!

The weatherman thinks the weather's going to be good here this weekend, so where will I be? - in Ikea at Bristol

Whizzpopper: I haven't heard many reviews of it yet, but don't forget about the 150 4-stroke from Yamaha as one of your thoughts.

I'm just about on the 100hr mark on my Suzuki 140 now, and it's still starting first time every time (all clever electronics start it up with auto-choke etc... and auto revs) - the thing is pretty much faultless. I will admit to having a few 'niggles' at first with the unit (stalling sometimes, under-revving at wot), but now I have the stainless prop on I feel that the boat is getting the best from the engine with some pretty good economy too. I really never thought that this 140 would be cheaper to run than my old 70 2-stroke, it's a great bonus

My first service @ 20hrs was approx 100, for lower section oil, main engine oil, and then labour - not too bad I didn't think. As yet, I haven't had to put any oil in the engine at all.... I just give it petrol, and that's it

-Alex

They are both going to burn loads of fuel - worry about performance and get a new two stroke engine, modern engines burn hardly any oil. Do'nt compare a modern 2 stroke to the likes of old Seagulls running on a 20% sump oil/80% petrol mix.

Don't to it! You'll feel afterwards. Went there once, never again! Don't even like their stuff! The store's crowded, you've GOT to walk round every display to get to the bit you want. The checkout queues are MILES long, carpark full, generally my idea of a bad day out

Don't listen to Richard B, he's telling you not to buy an Opti and he doesn't even know the model Range.......Just wait till I get him over on Boatmad.

I've got an Opti 150 (they do make a 135 by the way and are just introducing a 115 which is pollution compliant till 2008 and has a three year warranty) this Opti has been on the back of my boat and has put over 500 hundred hours so far. It get serviced when it's supposed to and never misses a beat.

The fuel economy on Opti's is exceptional we burn about thirty five litres an hour at 45 MPH with 5 up. Regarding the cost of 2 stroke oil the difference in price between an Opti and a 4 stroke bus a lot of Opti Oil which is more like about 5 a liter.

I wouldn't really consider putting another engine on a boat unless it was a diesel
