odd ...... Looking at the Kohler engine catalogue notice that the KDW series all have fans although liquid cooled but the KDI series are listed as mechanical (but are still liquid cooled) and don't have fans |

No, . . it's the sort of thing you're best walking away from. A questionable gearbox cobbled onto an industrial engine without any mounting brackets/feet to suit boat engine beds. The fan is what you would expect to find on any radiator cooled industrial engine. |

The fan is what you would expect to find on any radiator cooled industrial engine. Is that because they are designed to be installed with a radiator in front of it as per a car ? ...... I had been wondering if it was because it didn't have water cooled manifolds and the fan was to air cool them |

Reminds me of a wide beam on our marina that had a lump lifted out of a trashed Tranny. It was owned by a young woman who never ever took it for a pump out and every day she would use a pump to suck out the fluid from the top of the holding tank which was full of years of compacted shit.
Of course when she could not pump anymore liquid out she decided to sell up and the couple that bought it were virgin boaters who then found they had not only bought a boat but some hard to shift "cargo"
Phil.
Oh and it had a domestic oil fired boiler, a huge lump that sat at the foot of the stairs that demanded 240v and a lot of nursing

Unlike any engine built for automotive applications in which the fan sucks air through the radiator, the fan on industrial engines blows air through the radiator instead, . . because they're either stationery in such as gen-sets, or moving quite slowly and facing backwards in such as forklifts, so lack any assistance with air movement created by vehicle movement. |

My old boat had a Kubota in it with normal industrial manifold it worked fine the reality is industrial engines rev way harder than boat engines and survive very well. A lot of boats never break 1200 RPM in their lives genies can be running at 3000rpm for days with no problems

A lot of boats never break 1200 RPM in their lives genies can be running at 3000rpm for days with no problems A 2/3/4 pot diesel genny will typically run at 1500rpm/50 hZ a single cylinder petrol genny will typically sing its heart out at up to 3000rpm/50 hZ You are correct in saying a typical narrowboat instilation is undestressed - this is by and large due to the dreadful prop matching of the original boat builder, TonyDunkley has mentioned this numerous times; often it seems to fall on deaf ears... |

True but in other farm machinery its going quick, I was looking a 3 cylinder kubota genny on ebay and it was a 3000 one which I thought was a bit high |

True but in other farm machinery its going quick, I was looking a 3 cylinder kubota genny on ebay and it was a 3000 one which I thought was a bit high cheap genny's run at 3000 rpm, more expensive at 1500 rpm and you occasionally come across big old buggers that run a 750 rpm. reason is the cost of the alternators ..... 3000 has 2 poles (sets of coils) 1500 rpm 4 poles, 750 rpm 8 poles = massive difference in cost |
