90HP Merc Optimax

I'm looking to maybe purchase a 2006 Tracker Targa 175 with a Merc 90HP Optimax on it. I don't need a lot of overall speed, but I would like the boat to plane out like it should. It the 90HP enough? It appears to have a whale tail on it already. I'm guessing it's needed. Also, are the Optimax motors pretty solid? I've had Merc's before but never an Opti. 


Thanks in advance!

Optis were good motors. But just remember, you're looking at a 14 year-old engine. How it was cared for will matter more than anything else.


If the seller will go along with it, it might be worth taking it in and having a compression check done on it. Just saying ....

Boat will not be a rocket ship, but the 90 is plenty of motor to get up on plane and cruise.  I'd expect 40 MPH give or take a couple depending on load. Opti's in that class are easy on Fuel and Oil.

I used to own a 2004 Targa 17WT.  Bought it new and had numerous upgrades done predelivery, including the motor from the stock Merc 60 to a 115 Optimax.  After break in I switched from the BlackMax 19 prop it came with (No idea why that rig didn't come with a SS prop) to a Merc Trophy Plus 17.  Then I had the TP17 tweaked at a prop shop & it became a rocket ship!  Holeshot as in the 3-4sec range to plane, would stay on plane at slow/moderate speed, and didn't suffer blowouts in turns.  Top speed on GPS was about 42-44 mph.  One time coming out of a no wake zone I "cracked the whip" & punched around a slowpoke, cut over his wake & literally had the Targa launch totally out of the water.  Wife & puppy were not happy.. LOL!  In my opinion, the 90 would be ok with a tail on it , just not great.  The 90 should put you in the 75% range of max HP for the hull, mine was 125 max.  A 4 blade Trophy Plus prop probably would show a big increase in performance.  As far as the Optimax goes, it was quiet, responsive, sipped fuel, easy to winterize (no fogging for an EFI motor), and overall a great motor.  Only reason I don't still own that rig is physical disabilities made it difficult to launch/reload when solo fishing.  Really miss that boat!
