1969 20' engine choice

I run an E-Tec 175 on my 1976 MA CC and am quite pleased with the engine. I am on plane very quickly and have recorded a top speed of 51 mph at 5350 rpm on the gps. That being said I am sure that the 115 would do a good job as well. With the Florida rain storms I like to be able to get in quickly. With a 21" prop I cruise at around 3500 rpms at about 32 mph.

I haven't made up my mind completely but I think I may be leaning toward the 150 now. Over the 45 years I've been around boats, I have rarely heard anyone really unhappy about being overpowered but a lot of people are unhappy about being underpowered!

I once rigged for her owner a 20' CC, installing a 20" Merc 225 on a mechanical jackplate, with a low water pickup & nosecone. Cruised in the intercoastal at about 3800 rpm at 45 mph. Top speed was 62 mph at 6000 rpm running a 32" overhub chopper style prop.
The real story here? It was owned by 24 yr. old female attorney from Palm Beach who was given the boat by her Dad as a present for passing the bar exam.
It was fun to watch her flying down the waterway at 60 mph in a SeaCraft with a huge rooster tail behind her.

Do you need that much power? No, of course not. Sure is fun, though.

I think that would be a excellent choice, especially since I read the numbers above from the 175 ETEC, those are great #'s and I have a 200 Merc. Go to www.usavemarine.com and ask about the 150 ETEC, he is a big dealer and can ship it and give phone support if needed, might save some dollars but not sure where you are.
