motor weights, too much?

bushwacker, how fast will your 20 go w/ the 150?

50. His hole shot at 70% throttle is mindblowing too. Seemed like 2 seconds to plane. Very impresssive indeed.

The Opti's are just fine now as well, when you go to the V6 all the engines will be close in weight from 150 to 200, thats why I suggested the 115 HO - V4 and as much HP as the 130. The next big factor is the lower unit, the HO's are designed for smaller lighter hulls and it comes with the high performance Lightning gear case which has a smaller foot print and therefore faster too. I think it comes in about 370lbs so about 50 lighter than Bush's 150

I follow alot of boat forums on the net, Etec's and Opti's are seeing the least issues of all. The Etecs will also run @ 100/1 oil ratio and no dealer servive for 300 hrs, which is a fact not hype. Plus I can get you a good deal on Etec's if you can put it on the boat

Dixon-Don't you want the larger gear case for our heavier boats for better wear and tear?

I have the 175 Pro XS Opti, which is a tweaked version of the normal 175. I can spin 6000 rpms versus the normal 5600.

I've seen 49.8 mph on the GPS with just me and a full tank of gas aboard with the top down, running a 4 blade 20" pitch prop. A 3 blade prop with a little less pitch would probably be a little faster. Also has bottom paint on it which may cost some speed, but the bracket is probably worth an extra 2-3 mph. However in normal cruising/camping trim I'm loaded very heavy, close to 4000 lbs total, so I run a 15x15 4 blade prop in that configuration, which will push it to about 40 with the big bimini top up. As Sandy said, hole shot is pretty decent. A couple of months ago I ran 235 miles on the St. Johns river in the 4000 lb configuration and burned almost 50 gallons of gas, which works out to 4.7 mpg, so I'm fairly pleased with it's performance, considering the load I was carrying. With the 20" prop and a light load I'll average over 5 mpg.

I used to get slightly more speed with my old Mercury XR4, running a PowerTech 15.25"Dx16.5"P 3-blade. The motor was reman'd to about 190hp, but I couldn't get that kind of mileage. The ETEC is impressive.

200 ft. lbs. @3000 rpm, yeah that`s ok I guess. You can also winterize it in 15 mins by yourself.Winterize? Saw a rerun of Ship Shape tv and they toured the factory. You should see the size of the spider gears in the lower unit. Massive. BRP is the best thing to happen to Evinrude.

Oops, forgot about the 5 gallons we bought in Palatka! Corrected number is ~ 4.3 mpg!

I had a Yammy 175 carbed two stroke, it was about 420 lbs or so and I thought that was too much weight on my 20CC. I repowered with a Etec 115. Weight is good, no water comming in the scuppers.

I was able to do a fishing run yesterday two people and gear, 12 gallons of fuel, traveling about 15.5 miles on about 5 gallons, about 3 mpg. Light trade wind 10-15 knots, seas 4-6 feet 8 seconds, so only cruised at moderate speed, probably about 18 mph.

I tested it out today with a GPS in the bay, small chop and here are the results I got. Not all measurements were the same run and exact same conditions so there is some variablity but its a good ball park. 15 pitch SS viper prop.
