Anyone out there with Twin 150 Yamaha Motors?
Looking for some perfomance data from guys running twins on their 23' Tsunami or Sceptre.
Thanks, Jason |
Re: Anyone out there with Twin 150 Yamaha Motors?
I have a 23 Grady Gulfstream with twin 150 Yamahas. The performance data on that is a cruise speed of 30-33 and top of around 47. The gulfstream has an identical deadrise at the transom and is a heavier boat so your performance would be similar I would "GUESS".

I have twin 1998 Yamaha 150 Salt Water Series engines. They have carb's and like gas alot. They are on a 23 foot SF SeaCraft. I may average around 1.5 miles per gallon (if I'm lucky).

Thanks for the info. I'll put my numbers up as soon as I splash the boat.

PeterB, What props you running? What type of load do you carry.

Jason,
I have stainless steel 17-M props. For boat weight I come up with around 5,600 pounds (boat & t top = 3000 pounds) + (2 engines = 838 pounds) + (mostly filles 150 gallon gas tank = 900 pounds) + (3 fisherman and other misc stuff = 600 pounds) Also, I use 12x12 Bennett trim tabs What was the question again? Hope this helps. |
Re: Anyone out there with Twin 150 Yamaha Motors?
Thanks for answering my question. I too have the m-17 props. I have the same fuel, same motors (not installed yet). I have a Tsunami. I will be considerably heavier with scuba tanks. Just trying to see if i'll be propped right.
