Thanks for the offer Doug, let me run some numbers by my installer first to get his input. i ran today for a couple hours i am really impressed with how the boat just leaps up on plane and will stay on plane as low as 2500rpms Tim Stamm Photo Finish 1981 33' Bertram FBC

I am so jealous! I still plan on coming over and having a look. To have those numbers for Bahama trips would sure be nice. Don't know what I'll get soaked over there this year. We are just doing West End and Bimini, because of the fuel. May 27 to West End, June 17-25 Bimini. Run it across the ditch and come along. Dive, Dive, Dive, Fish, Drink, Drink, Drink...is the plan.

Ouch... That hurts.[V] Up on the North Shore of Mass, the temps never get that high. I'm lucky if my guage ever reads above 69. When we go to Nantucket in July, I hope the water temp will be that warm. When I was in Nantucket a few years ago in Aug the water temp was about 78. FYI: For any of you New England owners, we'll (the Queen Elizabeth and the Rebecca Rose) be in Nantucket the week of July 17th to Friday the 22nd. Feel free to tag along.

Tim, I just heard back from my friend with the 35 Egg. His trannies are Hurst 2:1 and he's running 4 bladed props. He wasn't sure about the size but he's going to get back to me. I was on his boat last summer and we were hitting 32 knots on the pins. I know you have 2:1's but I'm not sure which make. Got your email. I'll start looking into sending my spares down to you.

Tim, That's great. Now you're closer to what I thought you'd get. I knew that boat/motor combo had 30 knots in it. So what's next? Do you spring for the 20x18 4 bladers and see if you get even more. Regards, Doug L. 1986 33 Bertram FBC Queen Elizabeth

Doug, i am taking my 20x20x3 in today to add cup to them the shop that cut my props said he wouldnt charge me to add some cup which he said would take away 200 rpms .so when i get those back i will switch out props again and see what i come up with...i called general proppeler and they said the equal to 21x20x3 would be 21x19x4 however they were out of stock and would take 6 weeks to get. they were $1223.00 in nibral each....i did an overnight on sat. a great time and everything ran well.my speeds change depending on tides and wind..but he numbers seem to be close to the same fully loaded.

Tim, Look online. I.E do a google search for Michigan props. I bought my 20X18 4 blade Michigan Nibrals from a shop in Wisconsin. They were $900 a piece. Here's the link: http://www.propfix.com/ Regards, Doug L. 1986 33 Bertram FBC Queen Elizabeth Marblehead, MA
