I run an 97 Evinrude Ocean Pro 200.
Very thirsty.... 1.9 mpg (4200 rpm cruise) on a flat day with the wind to my back on a 22’ Grady. Really sucks down the fuel while trolling.
To put it into today’s fuel perspective, a fishing partner runs a 275hp Verado on his 24’ Grady. Same hull as mine, just 2 feet longer. Fuel consumption is almost identical....tilting in his favor.
The only real gotcha at this point are the plastic carbs
They’re pricy and getting harder to find all the time.
I’ve had to replace 4 out of the 6 due to cracks developing at the base of the mounting flanges. Got lucky and found a used set on eBay. Not cheap, but a lot less than the $550 each from BRP. Warped fuel bowls are also a problem although I’ve yet has that problem.
I would be very leery of a 25 year old motor with “low” hours.
Fuel and ozone deterioration of the rubber and plastic parts continue if the motor is run or not. Count on replacing everything rubber on the motor. That includes rebuilding the carbs, replacing.the fuel pump and all the fuel, oil and vacuum hoses on the motor.
Unlike a 4 stroke, problems in the fuel and oil delivery systems on a 2 stroke can/will have catastrophic consequences.
