I finally pulled the trigger and went with an 150 Etec hard to pass up that 7 year warranty.Just in case you are wondering shes a 1978 18 ft

Yup...gonna need more pics of that one!

More pics and specs needed. Original floor height? Does it still self bail? Speed and economy? Sweet 18!

Thanks,here are just a few photos of her resto ,I raised the floor 2 inches moved console forward 8 inches batteries under console and have no problem with self bailing.The motor has been on only 1 week at 3500 rpm 36mph and 4.8 mpg 2 men full tank gas 50 quart cooler.

Wow!! You did a beautful job on that resto.More pictures would be great.It sits so nice in the water.Congrats.

Those are pretty decent performance numbers! How is motor height (top of AV plate should be above green water), what prop are you running, and what is WOT rpm?

Just got back in town so went out by myself so I could not se cavitation plate but wot is 5200 rpm with a viper 14x19 40 gal fuel 50 qt cooler

If your AV plate height is correct, 5200 is too low! Most dealers seem to mount the motors too low, so check that first, but OPTIMUM WOT rpm for your motor is 5500-5750, so I'd be thinking about trying a 17" pitch prop. Also check your min planing speed, because it's nice to be able to slow down and hang on plane at about 12 mph if you're running offshore and the seas get over 3'! A lower pitch prop with more blade area and stern lift will typically help you do that.

i did check my min planing speed and it was 16 mph. Sorry my mistake wot according to my paperwork is 5440 rpm
