Good boat, but do a search on here and make sure you're aware of the things to be expected to fix and or check for prior to purchase. As far as the ocean runners I believe are similar to the ocean pros. Very thirsty engines but reliable and easy to work on even for non motor mechanics like myself.
They are carburetor engines, as opposed to newer managed fuel injected fuel delivery systems that are more precise and efficient. That being said, although they use a bit more fuel, they are nearly bulletproof and capable of being tuned, repaired, and kept up by diy owners, saving plenty of money for that extra fuel.
I have the same exact year/setup. The motors are damn near bulletproof and easy to work on. I don't have a count on hours on mine but, they are getting very tired and hoping to get another season out of them. I love the boat. I cruise at about 28-32 and currently getting about 0.8mpg. I know they were better when I bought the boat about 4 seasons ago. The compression is getting low on them and I am in the market for newer used power.
Wow, that's impressive. I have the latest tech,4.2 liter F250 and my 228 on the lake gets maybe 3.2 mpg. I had a 1998 192 with a Johnson Ocean Pro 150. That boat got around 2 mpg. I repowered with a Yamaha F150 and my mpg doubled to over 4.3 mpg. Not saying you're making it up, but I am saying those numbers are impressive for your set up
