    Weight is the same as a regular race set-up. Height, except J classes, is not regulated.

      Kilo Speeds

      Top Gun 3-Z,

      The kilo records are listed on the APBA web site. They are:

      CSR 69.787 mph

      25SSR 74.493 mph

      500MR (CMR) 82.558 mph

      These speeds are most likely about 10 mph faster than your competition speeds.

      Call Darrell Sorensen, he knows what you need. You will need a "special"
      wider bottom boat, often called a "Floater Boat".

      And you will need "BIGGER" propellers and "jack" them way up!!!!!! Call
      Craig Dewald.

      Good Luck.

        I always thought it odd to allow the kilo records to be set with no height restrictions. It would seem more relevant if the set ups matched the competition restrictions........just a thought

          Kilos....

          The kilos answers the age old question: "How fast will it go". That is one of the first few questions that someone will ask when they see your boat. What do most racers generally give them for an answer? Almost always the Kilo speed for your class. Most people don't lie beyond that.

          But more seriously- the kilos are most like the "boat version" of the Bonneville Salt Flats speed records. Special boats, propellers, set-ups and sometimes special lowerunit designs are required to gain speed. It has always been like this since the beginning of outboard racing. Often times- a boat that goes that fast can't turn... and if you can turn it, it can't go fast enough!

          I set a record once. It was with a special boat and all... and it couldn't turn!

          Matt, I remember you from long ago......!

              Like Bonneville except that Bonneville is about 4000 ft above sea level if I remember right and really good kilo courses are much lower for more engine power, ie Devils Lake OR which is right at sea level. While special boats are needed in some classes- notable the fishing boats classes, a good hydro can be set up for a kilo in some cases. I set a CMH kilo record at Parker AZ in a boat that won National Championships in 20SSH, CSH and CMH as well as setting competition records in CSH, CMH and 25MH. I don't know how high Parker is but there was frost on the boat when we put it in the water so it was cold for plenty of power. If we were to try it again, I'd build a special boat but an ordinary hydro can be made to work in some cases if you pay attention to details.

                How high (prop shaft for 20SSH or CSH) would you run a Yamato for the kilo. I've never been to a kilo, but it kind of intrigue's me.

                  Don't know, because we never ran a Yamato in a kilo. The CMH kilo record was set with Dick Engler's Merc- an x-Jerry Wienandt block. We always went faster with a Merc than we could/can with a Yamato. Even now, our Yamato CMH is down on top speed compared to what we did with the Merc. HOWEVER, the Yamato is so much better around the race course it is easily superior in race trim. We used to be able to run a stock 302 with the center of the propshaft level with the bottom. Not easily done but possible. Never won a Nationals with it but we did send Brian P out to a Winternationals in Bakersfield where he killed everyone. That was the only big win with a 302 until this year. We lost our edge with it when the low and then lower height limits were approved by people who weren't good at solving the puzzle. You might be able to run that high in a kilo if you have a boat that runs bow high but if you have a flat running boat where the bottom is free in the back, you won't be able to get that high because the water pickup is higher when the boat rises up. Temp gauge is really useful. We could survive at 417 but stick at 420 with the stock 302. Sure, we ruined some pistons learning how to do that but the factory has replacements. We even found that repaired scuffed ones can be better than factory new ones.

                    How High???

                    Sean,

                    Ask "How High" to Wart. I think he has all the Yamato records.

                    He knows how to run them high without sticking. By the end of the kilo run, I'm quite sure the motor is running without cooling!!!!!!!!

                    Good Luck.

                      Kilos....

                      Thanks Dean- I was thinking the same thing about the S.O. Yamato engines. If you go much higher, you run out of cooling water. Dean actually was one of the first people that I know of to make a more specialized boat for Kilos. Way back when I had a Casta-Craft ASH... and people were still running the Sidson and a few Marchetti boats in ASH, Dean came out with a very small hydro that was way ahead of its time! I remember seeing it on Dick Ficketts trailer and thought it was a J hydro! This boat that I remember was very similar to todays ASH boats only it appeared about.... what 30 years ago? Dean was a very successful record man himself.

                      As for a special boat for kilo boats... you can do it with a regular competition boat, but you will go faster (and maybe safer) with a special boat. The idea is to improve streamlining and reduce parasitic drag.

                      My story was with a PRO 250cc Runabout. I was down to the kilos in Moorehaven with Mitch Meyer trying for the same record. He had set all of the competition records and won the Nationals too! His 250cc engine was the best in the country and maybe the World. He ran through the kilos with his competition boat (no turn fins though). I had an engine that was competitive on my hydro, but not as powerful as what Mitch had. The difference was my "special kilo boat". I designed the boat so that I could laydown in it (laydown runabout in 1987). The boat was only about 15" high, had a 5' long clear windshield that enclosed my helmet and had a fiberglass cowel that covered my body and streamlined the engine. The speed difference was 4+ MPH! I could have gone even faster with Mitch's engine and some additional testing. Special boats work.....!

                        Stock Outboard is all about a level playing field.

                        True parity is one motor per class.

                        It's RACING, not just another boat ride!

                          Thanks

                          B1 Pro Racer,

                          Thanks for the kudos.

                          Now let's see. Northborough, Massachusetts?????

                          Who are you please? Or, give me a clue.

                          And, "parasitic drag"...... sounds way too technical for me!!!!!!!!!!!!!

                          Thanks, Dean

                            Not Crowley.....

                            No cigar for you, John

                            But you definitely know who it is, try again.

                            Hint: he was very active on the old rec.boats newsgroup and comes from a very distinguished racing family, but is always a bit under the radar.

                            Whats your next guess?

                              Kilos....

                              John was right... it is Peter Crowley. There are few families as distinguished as the Runne family in any kind of racing. Between Hank and John's Mom and the three boys, they have been a successful family that are a asset to the sport of outboard racing. In addition there is another generation of Runne racers coming along....

                              Brad are you related to Bill Walker of Connecticut racing fame? Bill would have known who I was....!

                              Dean might be modest and quiet, but he was way ahead of his time. His work had an influence on me and we lived across the country from each other. I remember your boat on Dick's trailer- you had lettered "UIM World Record Holder" on the side deck... I was full of envy! At the time I wished that I could put that on my boat! Of course it wasn't the lettering but the result of all the knowledge, funding, work and time it took to earn the right to put that on your boat. I was impressed to say the least! Many years later after my share of knowledge, funding, work...... I put that same lettering on the side of my PRO 250cc Runabout..... and I was proud to do it!
