I read that you were looking into changing props, did you ever consider the Enertia Eco? I have seen some good reviews on them. I am considering buying a spare set as we will be taking the boat from Fort Myers to the Keys for 2 weeks and I thought it might be a good idea.

The answer to your question is No.
At the time the new Merc 350's and 400's were introduced there was an immediate need for bigger props. Nor-Techs like Merc Rev 4 props even though the new engines can spin Bravo 1's unfortunately they don't handle as well as the Rev 4's. Then Merc debuted the new Rev 4 XP which is the prop I hope to test later this year.

I tried them on my boat, they are good for .2 mpg increase which is about 10% in my case. I bought a set of 23" and they run about the same as my 26 Bravos. Speeds are similar but I am spinning more RPM to get the same mph with the ECO's. My Bravos have had a lot of cup added though they are probably closer to 27". I like the ECO's but they do vibrate more and are noisier than the Bravos. I just got them on so until I run them for a while I won't be sure if they are better all around, but MPG wise they are better all around.

What boat and engine combo do you have?

Spectre CC w/ Diesels last I knew and as listed below his screenname.

Yes 37 Spectre with Yanmar 6LP (315hp) and Bravo X drives.

Needed a little more space. New phase of Hyde Park III due to be complete in June. Have to wait until after the close to build the loft and bathroom as none of those items were on the original plans.

Current unit is 20 x 55', this one 20' x 60' but b/c it's beside the corner unit it's actually 28' wide at the rear wall. The extra space will allow truck and trailer to be backed in together + more room for a vehicle parked beside the boat.

Added more lighting and plan to have a HVAC supply trunk built fore / aft to better distribute the heating and cooling.

First there was 34-58 and soon there will be 34-98, exactly 50 builds apart. I was really hoping for 34-100 but no such luck.

New boat storage beginning to take shape as well.

What did you do with your old storage? Can't imagine it getting much better than that.
