Should I purchase a 2 Stroke 90 HP Mercury Optimax?

[shimmy]

Hey all, looking to buy a boat. Just wondering if it is a bad idea to buy a 2009 2 stroke 90 HP Mercury Optimax as opposed to a 4 stroke? Since motors are going this direction of 4 strokes, it may be hard to find parts for repairs? Thoughts?

I have a 90 hp Optimax on my 19 ft. Tracker and love it. Never owned a 4 stroke, so I don’t know what I’m missing. Have not had any problems with mine. I use good gas, oil and additives to mine. Knock on wood my 90 has been great for 10 years. 2012

I'd say you're okay.  I didn't have trouble finding parts for 2001 115 Mercury or my 1998 2.5L Promax - both 2-strokes.  Mercs are pretty well supported.

That is a good motor, you shouldn’t have any trouble finding parts

This place has parts for Merc engines back to 1940

If priced the same, I would get the 4 stroke but getting parts for the 2 stroke won't be a problem  for years

Merc is fine for getting parts, probably the easiest actually. I do love my 4 stroke though.

Two stroke outboard engines worked for over 100 years.  Mercury is not going anywhere and service is easy to find. However, the advantages of a four stroke outboard are many.   If you plan to keep the engine for a long time, you may want to step up to a new four stroke.  Fuel economy is better, they run quieter, they come with a warranty, they idle all day without hesitation, no need to add oil to the gas and they don't smoke or pollute the water.  The difference is amazing.

Who'd have thought Evinrude would stop making outboards after 110 years?

That’s a different color horse.  In thr 90s OMC outsourced a lot of parts to overseas (China) I think.  They had lots of problems.  Genmar then bought them out and tried to resurrect them.  After them came Bombardier, a branch of the Leir Jet people.  I spent 2 days in a district meeting with them and they wouldn’t even entertain ideas from the midwest.  They marched to their own drummer.  I wasn’t surprised when they pulled the plug and decided to play another game.   I’m surprised they didn’t do it sooner.

The 2009 Mercury Optimax 3 cyclinder 2 stroke is basically 1/2 of the 200hp Optimax. This engine uses the same block as the 75hp, 90hp, 115hp and 125hp engines.

I owned the 2005 115hp Opimax 20” for 15 years without any issues, excellent engine, great gasoline mileage and quite clean running for a 2 stroke OB.

I ran a Laser 2, 20P for my Triton TR-175 with good performance about 55 mph top speed, usually traveling at 35 mph lake speed limit.

The 4 stroke is a heavier engine, 365 lbs vs 300 lbs, very quite and popular.

Customer service support is excellent with Mercury engines.

I had nothing but issues with a 08 75hp Optimax. The engine would always have a miss at idle and was told by the dealer that this was normal and that most opti’s do this.
