If you own an Optimax.......

....I hope you'll assist and answer the following concerns I have about a new RIB I'm looking at with a 2001 Mariner 135 Opti on the tail.

The current owner is being very straight with me and has advised of the following problems. Perhaps "the forum" could assist in eleviating my concerns.

This is what he's told me. It's a 2001 with 36 hours.

1. The water spout is very weak on tick over but like a jet wash under revs.
"should this concern me and if so, what is the remedy and the cost of the same"?

2. The instruments have several settings and read outs which appear to be out or sync' in that when it's full of oil it advises it's empty.
"With only 36 hours is this to be expected and again what is the remedy and cost of the same but perhaps more telling, may I ask why after only 36 hours has this occured"?

3. With the above in mind (3) what instruments would they be and what information would they adivse.

A lot of questions I know, however, I'm about to invest a tidy sum and would appreciate your assistance as I will be simply turning up with a bucket of notes and driving away a short while thereafter.

I'll chip his price a little for the cost of any repair / service required, however, I need the ammunition to assit in the same along with the confidence that it's not too much to worry about.

Finally, are these engines as quiet as a 4 stroke ?

Cheers.

Opti 135

Hi, I drove over 1000 miles with Optimax 135 last season and it worked fine. A nice engine. I can't answer to your questions, in our engine with 170 hours we had no similar problems with instruments. Water spout is not of concern I think, some engines just tend to work like that. But I would like to warn you about spark plugs. They are very expensive and have to be changed every 100 hours. Cost is high, I can't remember exactly but like 100 pounds each is close to correct. And if you don't buy those Iridium plugs and go for ordinary (=cheap) models instead, get ready to change a new plugset every 20 hours. Anyway, ask for your local Merc dealer for more info, they may have gotten some alternative plugs that might be long lasting and lower priced.

The engine ate a lot of oil also, after calculations a medium concentration was close to 3-4%. There were no problems still, just frequent oil refills. Final explanation for high oil consumption lacks still.

.....I didn't want to increase my wrinkles with the constant factor a TVR would bring. If you've ever met Phil Davies you'd know where I was coming from.



Love ya really P.D Ain't it great when a well respected Forum such as this posts your own "smiley" look alike face ?

Source your plugs from the states

Spout isn't anything to worry about it is a bit poor when ticking over, as long as the temperature is OK of the water and the block isn't too hot to touch.

most problems with spouts are sorted with a new impeller and thats a minimum cost.

Oil reading can be sorted by recalibrating the gauges, the manuals tell you how to and it's easy peasy. Unless you are in sales.

No new gauges needed,but I am a bit dubious on the 36 hours in 3 years, nobody buys an optimax and leaves it on the hard. one just can't stop driving em, 12 hours a year seems awfully light use. In fact it's still 64 hours of it's service and should be absolutely spotless and shiny.

What I think has happened is that it has had it's EUC replaced which has the wonderful effect of setting the trip to a big fat zero. It was quite a common thing for 2001 engines to have them replaced. I also have heard that the trim and tilt was faulty on that year.

go for it

You can download the operating manuals from this website:
http://www.marinepower.com/

This tells you how to calibrate the smart craft gauges.
Trim reading on ours is a bit iffy sometimes.

Our Opti had only done 70 hrs in 4 years but the condition seemed to match that of the RIB (Immaculate) so I didnt worry about it.

Put mine in for service and they replaced the spark plugs with cheaper ones the philosophy being replace with cheaper every year or expensive (about 30 x6?) every 100 hours. The guy who did ours reckoned that the users who replaced every year thought they ran a bit smoother dunno. Service including parts and labour was about 300 I expect you will probably get it cheaper where you are we get ripped off down here.

Nosier than a four stroke at idle? - Probably a bit but not obtrusive I was firmly in the four stroke camp until we got the Opti. Family can sleep next to it when were burbling up the river but the real point is the gorgeous sound it makes when you open it up Im grinning just thinking about it.


Tue on this forum has given me advice before Im sure he will have something to ad.

(Wasnt the Medline sale a fishing trip?)

Oh and agree with Mr Wave go for it
