I desire to upgrade to a 4 blade high thrust prop. I feel there is too much slip with the stock 3 blade prop.

My first choice is the Tohatsu 4 blade 10"DX7"P high thrust (Part#3ZOB645143)

I am also aware that Solas offers two 4 blade high thrust props for this motor:
- 10"DX7"P (Part#5113-100-07)
- 10"DX5"P (Part#5113-100-05)

My first choice would be the Tohatsu.

Any advice would be appreciated.

I have a 20 hp Tohatsu and changed it to your first choice the 4 blade 10"DX7"P I guess you could say i was over impressed as it gave me way to much bow lift. I switch back to the 3 blade that it came with and use the 4 blade as a spare now. For me on a 23 ft Irwin was more than i needed that being said I'm a bit over powered anyway.

Indeed. The 3-blade unit for the 4/5/6 is very good. Just not as sophisticated as the 4-blade units for the 8/9,8 and 9.9/15/18

Incorrect. Look at one of the HT props. HUGE blades, negative rake... Moves a LOT of water at slow speeds. Dee http://www.rubexprops.com/prop-info/...ust-propeller/

Completely different animal. the 4-blade prop for the 8.8 absolutely shovels water at slow speeds. Still the 7 pitch would be the best choice for that boat.

Nope. Probably allow the motor to go right up to 6000 rpm though. The prop has 4 EE (elephant ear) blades. However, the 7 would be a better choice, and is the prop the factory recommends for that application,

What other engine certifications do you have? Lot of people doing the Great Loop might be interested.

Simple,

You are 100% 0n the right track!

The special 4-blade HT props for both the 8/9.8 and the 9.9/15 are fantastic for sail applications. They have 2 major characteristics that make them the best choice: 1. Huge blade area, combined with low pitch make them "shovel" water at low speeds. Also, 2: The over-sized hub allows the exhaust to stay off the blades when in Reverse, so the motor "bites" into clean water, giving Stellar reverse control. We install a lot of them, and have had Zero complaints -- all compliments! For your boat and motor combination, I would recommend the Tohatsu/Nissan 3Z0B645143, PROPELLER (7) 4 BLADE X 10 X 7 (F15/20C), which has an MSRP of $122.58, available from any Tohatsu/Nissan dealer (including me). FWIW, I personally have one of these type props, in 5-pitch, on the 9.8 on my 7,000-pound HR-28, and it out-performs the old 15 hp OMC motor that had a 3-blade prop. You can drop me an email at the officeaul@obersheimersails.com, or call 716-877-8221 M-F 9-5, and we can discuss the situation.

I have the 7" pitch 3 blade on my Tohatsu 6HP 4 stroke. I change from the stock 9" pitch (I think) prop to slow down the trolling speed. It also increased my top speed by .5 MPH. I think the 5" pitch might put you into the rev limiter, if it has one.
