turbines are cool for lots of reasons but that noise issue HAS to be addressed if you ever want to see them in anything other than a "exibition" type setting....... I was at our ramp a couple of yrs ago and a guy had a turbine boat and I have seen the Unlimiteds run.......personally I thought this guys boat was cool, but trust me there were LOTS of people around who didnt (park like setting with restaraunts etc).......I couldnt imagine having a place on the water and having him as my nextdoor nieghbour........we got enough cops and insurance companys sniffing around our sport........keep going full speed on the noise thing.....that will be the turbines downfall.:)

rocketboat, do you have any pics/vids of your turbine SeaDoo? :cool: :D

awesome thread! :cool:
Do you envision gas turbines prices becoming more reasonable with further marine refinements? As well, is it true that they burn fuel at the same rate at idle as they do running high speed? Last year I got a quote for 90K for two T53s L13Bs 1600HP These were marinized versions. Compare that to two Merc 1075,s or maybe some Sterling 1200s |

They do not burn fuel at the same rate at idle as they do at full speed... this is a myth. It is based on the fact that a turbine engine typically idles at 45% of its maximum rotational speed. The fuel burn is still high, but not as high as at full throttle. If fuel burn was the same you would be releasing the same ammount of energy... and thus there would not be any point in having a throttle. |
Hay gerry thats what i used to do worked at willaims international in walled lake michigan. we built the turbine engine for the cruise missle tomahawk .i was in r/d ran them in test cells and tore em down and built em and tested em. was real ,cool them we did small buisness jet engins faa certification bird strikes and hail strikes and shaft seperation way cool stuff.

Thanks for all the info. This is awesome.
A few more questions: If you have T53's, you can still use #6 drives ? But what when you use T55's ? What kind of drives? What kind of tranny can handle that ? I've read about mid-size yachts that use Turbines and Kamewa Waterjet propulsion? How does that work? Can that work in offshore powerboat applications ? |

Pretty cool! Keep a look out for some L13b,s for me:drink: |
Knot-Right... called your cell earlier today. Have a pair of L13B's available... 705-790-7702 let's talk!

Can that work in offshore powerboat applications ? the Upper shafts have a 1/2 inch twist to the splines. This is evidence in the throttling problem in the turbines. Not to mention the amount of torque being applied to the drives. The lowers in my sixes are missing more teeth then a montana redneck.:evilb: OSO member Marinetrans has the parts all over his bench. Maybe if he see,s this he will post a picture. Arnesons would be a better choice or a fixed drive such as the BPM. |
