| Post subject: | dual motors single prop |
I'v been contemplating on building a mud motor for my small boat a long tail is my choice on the type. As far as hp more is better right? but is two better then 1? I'm looking at 2 HF 6.5 hp engine join together by a chain on a go cart type clutch on each motor and one sprocket in the center with a pillow block attaching the shaft. Pros. More hp for less money useable clutches changeable gearing for more speed out of the motors cons Slightly more weight more parts to brake I would like to achieve the speed of a short tail but the abilities of a long tail. Here is my questions to you all Have you ever seen anyone attempt this? Attached my concept for the idea |

Interesting concept, I've personally never seen anything like it. Best of luck with this build I'll be watching to see how it comes out! Sent using smoke signals |

Seems like it would be tough to keep both motors perfectly in sync. Good luck Sent from my SAMSUNG-SM-G891A using Tapatalk |

I don't want to sound negative or rain on your parade...but I think the only reason to do this would be for the satisfaction of doing it and having something unique. I don't believe it would ever be as reliable as simply using a 14-18hp single engine and drive. The more moving parts, the more problems. If you take it on though, it would definitely be a conversation piece! |

You have a good idea for a clutch on each motor, that will eliminate any rpm differences. I would suggest belts over chain though. |

Almost all Navy ships use two engines per shaft coupled through a reduction gear and in design aren't that much different than a long tail, just with inboard engines. With clutches, I see no reason why it wouldn't work and it should weigh less than using two longtail engine setups. Weight of a 20hp LT vs. a twin engined single shaft LT? Shouldn't be too much off. What I've noticed here lately is that there are a whole lot more performance parts for smaller engines than there are for larger HP engines. Joel norcal |
