Re: Tennessee power
I had a Yamaha 9.9 high thrust on a Bolger/Edey & Duff 29 foot
Shearwater yawl (#7) which would do hull speed (6.5 knots +/-) at
about half throttle and 12 miles per gallon. Loaded displacement was
about 2900 lbs, beam 6.5 feet, flat bottom, large radius
chines,leeboards up and rig standing. By the way this same engine and
boat are extensively used and still performing well for the current
owner 21 years later.

this is realistic? How does she handle with a larger motor like the
Honda 25 without the large high-thrust prop? Unfortunately, Yamaha
has a high-thrust 9.9, a 50, and nothing in between. Thanks Sam

I am also amazed that Bolger specifies a 9.9hp motor as minimum
feasible power on my 31 foot long Topaz Spyder runabout.
I am still plugging away on my Topaz build, and have opted for the
high end power (90hp Honda) because I want to pull water-skiers.
- A 9.9 HP will push 5000 pounds at displacement speed, that's
probably why he spec'd such a small engine as a minimum.

- I recently found out that Yamaha outboards are made in China under the
name of Parsun. They are cheaper and from the outside exactly the
same.The longshaft are the same price as the short and can be purchased
with remote controls. Don't know about the insides or warranty.
" Hello Sir, the following is the pricing for a 9.9 and 15 electric
start long shaft with remote controls.
