Any comments?

Does anyone have any experience of this engine (2003 model)
I've heard different views so far and wonder if anyone would care to comment. ???

i just got one!!!! the saltwater edition

will let you know when i get it on a transom.

Seems to be confusion over pick up from two to four cylinders.

I'm not an expert on the 115, but apparently the one that picks up on the carbs is'nt very good.

mercury optimax 115

Used the new 115 optimax on a 6.2 metre Valiant in October, i thought it was a great engine. It had more power and grunt than the Yamaha 115 two stroke, better fuel economy and very quite.

The new Mariner / Mercury 115 Optimax is a 3 cylinder (in line) 1500cc block.

Will be collecting mine on Saturday..............should push the boat along a little faster than the current one.

The optimax 115 is a 1.5L inline 3-cylinder engine, it's about 10lbs lighter than the merc. 4 stoke (inline 4-cylinder). From what I hear it's faster than the 4-stroke, gets the same gas mileage, and it's just as quiet! Both great engines
I was about to pick up the 115 opti, but decided to go for the 135 opti.

No it does'nt Daniel. I picked the 135 over the 150 because their was a $2,000 difference. I wanted the 150, that's the max rating for the zodiac. I also talked to a few guys who run the 135 and 150's on the same ribs and told me you wont notice the difference.

Cheaper yes, but physical weight is the same ... the 135, 150, 175 are all 195Kg, i had the same decision to make and the 150 came in £3000 less than the 175.
