Posted: Mon Apr 10, 2023 4:34 pm Post subject: Venture 26 / Honda 150 Prop Suggestion |
|
|
With a clean bottom (w/ bottom paint) and full tanks of fuel I'm barely hitting 30 MPH and 5,100 RPM on max throttle. I'm running a Honda SS 4-Blade 14 1/4 x 15 prop.
I've read some of the suggestions on C-Brats but many involve adjustable pitch props or are not clear about 3 or 4-blade recommendations.
Can any Venture 26 owners suggest a prop for the Venture 26 / Honda BF150 combination? I'm running at sea level.
Thanks! |

I wish that I could help, but my 26 has a Honda 225 and the prop is stainless 3 x 14 1/4 x 17. _________________ Steve Baum

You want your Max RPM to be in the 5500 to 6000 RPM range. This would require dropping the pitch by 2 inches. Or by going down one inch and a 3 blade prop. Let's see what others with the 150 (not real common--most have a bit more HP). But to hit 30 is very good with the 150, and suggests that your boat is light weight. You really don't want to run these boats over the high 20's. If you want 35, then go to 200 hp. But you will find the ride is not comfortable or stable as you reach the higher speeds. _________________ Bob Austin

My 25 fully loaded barely gets to 26 kts. I have a Yamaha 150. I've ran two aluminum 3 bladed prop sizes. The Solas Amita 15.5 x 13 and the Quick Silver Black Diamond 15 1/4 x 15. What max WOT RPM does your operating manual say you should be hitting? If in fact 5500-6000, you would need to drop down as Bob mentioned. But I don't think you'll pick up any more speed. If your boat acts as mine does, I suspect you'll actually loose a knot or so of speed by dropping prop size. You will however allow your outboard to reach it's WOT, which means it's not working quite as hard. Colby |

Thanks all I really appreciate the feedback. I clocked 30 or 31 MPH so about 27 Knots with 70+ gallons of fuel on board, two adults and one kid. So not the lightest of loads but no camping gear and no water in the tank.
The manual says 'full throttle range' is 5,000 to 6,000 RPMs so technically I'm there. Just seems like it should be in the 5,500 to 6,000 range to me.
I'm not looking for speed, I named her Sea Slug for a few reasons . I just want to be sure the engine is happy and I'm getting decent efficiency. As sailors we feel like we are going fast at any speed.
Its a 2007 BF150 with only 370 hours on it so I plan to ride this one for some time before bumping up to a slightly bigger motor.
I have an aluminum 4-blade 14 3/4 x 15 that's never been installed but seems like this is going in the wrong direction. |

My ‘22 26’ Venture, topped out at 43mph with a day trip load. Trimmed out at 5800 rpm.
Handling at that speed was rather light! |

Agree, You are getting adequate numbers now, but if you load the boat for a month's cruise, you are probably going to be lugging the engine. I would stay with the 150 for its lifespan, and then go to a 200. I. would get a prop for "altitude"--and see what that does. (2" pitch reduction.). Every outboard boat needs to have a spare prop and the tools/extra nuts/spacers etc to change it.

Excellent numbers, and shows why the 25/26 are a little underpowered with the 150, when fully loaded. (My first 25 had the 130 Honda; same block as the 115). Definitely underpowered. But survived for a month in AK,, and max speed about 19 mph, with no issues. I you never load the boat beyond short trip or day trips, then no issue. The C Dory line is sensitive to weight. |

kcassal,
What Bob mentions as C-Dory boats being sensitive to weight was especially true for us. With a light load, low on fuel and no water, we were fine with our original prop but with a full load, full fuel and water, we could not get to the recommended rpm range at full throttle. Only when we dropped the pitch by 2 inches were we able to get back into the operational range with our normal weight in extended travel. The original prop along with the purchase of a prop nut kit is in our emergency storage compartment. One additional purchase was a floating prop nut wrench which I thought might come in handy if I needed to make a prop switch from our dingy vs. a regular wrench which would sink to the bottom of the ocean floor if dropped. _________________ Gary F

If you are interested, I have 2 SS Honda props left over from when I repowered my CD25 from a Honda 150 to a Yamaha 200. Let me know if you are interested. Price will be very reasonable

I'm interested in trying a 3-blade vs the 4-blade on the boat now. Seems like it would get RPMs up. Obviously pros and cons to both. Probably the 14.5? PM sent. |

kcassal,
I will PM you, but here are some photos of the props (it's easier for me to post them here than in a PM). Both props are in excellent shape; nothing is bent or anything like that; just a few tiny nicks. The 14.5 will give you slightly more WOT RPMs; the 15.5 will give you slightly more speed. And yes, I have found that the WOT RPMs are higher with 3 blades vs 4 blades (I've had both).
14.5 inch pitch
15.5 inch pitch

I now have Sandy's S3x14.5x15R from his old motor. The prop is in new condition and I'll report back after testing.
Current prop: Honda SS S4x14.25x15R
New Prop: Honda SS S3x14.5x15R
Should be an interesting comparison. I'll let ya know.
Thanks Sandy! C-Brats are great! |
