chrisd4700 All Messages By This Member #372 Hi folks, I currently have a Yanmar 2GM20F in my T-27 and it drives a two blade prop. This set up gives me very little power vs. vibration. I'm wanting to switch out props this summer. Has anyone gone to a 3 blade prop and if so, can you give me the details? Size, pitch, etc. Are you still running with the Atomic 4 or has anyone else repowered with a diesel. I need some advice. Thanks in advance! c
Matthias Klemm #373 Hi Chris, I have a Universal M3-20 (3cyl 18hp Kubota) with a 3 blade prop but I don't know the size and pitch. This setup pushes the boat?to 5kts?at 1500rpm and?to 7kts?at 2000rpm.

Chris Antipas All Messages By This Member #374 开云体育 I keep an eye on the sight, having enjoyed my T27, Skywalker, so much over the years. My T27 was powered with an A4, and I put on a Variprop 2 blade feathering prop.? It fit in the aperture and transformed?the boat's performance.? When I sold her, I kept it because I thought it would fit on my new C&C.? Unfrotunatelty, the C&C has a reduction gear, so it didn't fit. ? I still have the prop if you are interested. ? By the way, how's Harry doing with the boat?? ?

chrisd4700 All Messages By This Member #375 Hey Matthias, That's the performance I'm looking for. I currently push around 4.5 kts @ 2000 rpm. Horrible! I understand the two blade props are really inefficient. I've read a bunch and well... I don't have to read much, I experience it every day. I'm on an inland lake / water way and when I'm coming back up the lake, the current really bumbs me out. I'm not moving like I should. A three blade is most likely in my future. Of course, I'll get all the posts about the extra drag but I'm not concerned. I'm not racing that often and from what I read on most of the prop sites, it's about like draggin your hand through the water. When I get good enough at racing that boat to worry about that, we'll talk. Right? Anyone else that has some experience on this is welcome to chime in... I need the advice, suggestions, opinions... thanks
