optimax 150hp

[spartan]

Hi all wondering if anyone can shed light on longevity of these engines mercury optimax 150hp any problems, thinking of getting one, who out there has the most hours on theres?

[Searider]

We have a 2001 with, I think 640 or 680hrs.

Generally pretty reliable.

Only problems have been:

Running a little hot at displacement speeds at the beginning of the season. New impeller sorts that.

Random relay failure. Engine just wouldn't start. New relay sorted.

HT lead chafed through causing small loss of power. Took ages to find but cheap fix in the end.


Still running well. Reasonable on fuel and fantastic torque.

Been really happy with it.

The biggest downside to me is they're very noisy at idle. compared with a fourstroke. This may not be an issue for you though.

The Harbour patrol in Christchurch have this Opti and the service Guy tells me the hours on the engine is now 1200+ !

Fantastic torque and speed. Brilliant V6growl through the mid range, but quiet enough on the plane or at idle. Slightly noisier than 4S but heh, they aren't like the old oil burners. Quiet enough for us. Pretty good on fuel too, IMHO.

We had a lead rub through the rubber, which caused intermittent power problems also. Not sure if it was the HT one. PITA, but once sorted all excellent.

Thank you for all your help but the one I was going to buy has gone.

I think Tim Griffin on here got over 3000 hrs out of his 150hp....

He would need to confirm that mind

Cracking package the 150.

Have a few customers with 500 hrs upwards showing on them and still going strong.
