Default Food for thought-Nitro RC boating needs some help

Let me preface this by saying Nitro RC boating is suffering from a multitude of maladies....

I am not trying to start a sxxt storm here...."JUST SIMPLE FOOD FOR THOUGHT"...
Nitro racing is declining and it isn't just because of FE and gas availability...
A great part of this decline is just the high cost of equipment and fuel....
The financial investment and experience required to try nitro RC boating just is not conducive to attracting new boaters...
How many of you are tired of paying $450.00 for a Novarossi 3.5 powerhead or $550.00 for a O.S. to race nitro outboards..... Outboards that could be out of production in a heartbeat....
I have been doing this for a long long time I have seen the RC nitro boating community dwindle for a long time now....
Nitro RC boating needs a good shot in the arm at "grassroots club level"....
We saw a bit of a grassroots revival a few years ago with the RTR boats like the Budweiser and Miss Vegas but that market quickly dissolved....
The next step up from RTR into nitro RC boating is a big one if you want to be competitive....
We don't see the young people coming into Nitro to keep the RC nitro hobby healthy.....It is just simple numbers...The more hobbyists that try RC nitro the more we will retain....
When David Hall and I introduced the JAE hydros 13 years ago we knew there was a ton of .12 car motors not being used so we designed a simple to build cheap boat to put those motors back in service .....
The introduction of the JAE gave a big shot in the arm to Nitro RC boating....Using that same approach we decided to try and put the million not being used .28 car motors into Nitro RC boating..
The photos you see here are photos of a prototype of a .28 outboard....If you have a 3.5 tunnel with a K&B , O.S. or Lawless 3.5 lower unit you can put it back into competitive service with a .28 car motor....
There are a bunch of 3.5 tunnels not being used because you have to put a $550.00 motor on the back to be competitive....There are 3-4 for sale on ebay every day...
What you see here is a $39.95 motor mount from Fred Howe @ Lawless Drives.This mount is completely adjustable..... Any .21 or .28 car motor with a SG shaft will fit on this mount....Mount comes with a coupler to the stock flex cables...
This pipe required a minor mod to work but more on that later...fact is it is $15.00....The car pipe [silencer] is from ebay for $15.00.....

https://www.ebay.com/itm/RC-Car-Exhaust-Pipe-Exhaust-Joint-Tubing-for-HSP-HPI-Redcat-1-8-Nitro-Car-U0W6/164021623249?hash=item26307359d1:g:HScAAOSwilNeFE9 z

If you don't have a motor you can get a new one from $75.00 to around a $100.00.....Parts are cheap and plentiful....
All the car .21's and .28's Buggy motors with SG cranks have the same mounting dimensions and platforms....
The motor you see here is a $$99.00 Hobao pull-start ....I put on the roto-start just for convenience..... The carb on this motor is a Novarossi 5 port rotary carb...


These motors are not junk....Machining and material is first class...These car motors are tortured by their owners in off road buggys & truggys and they survive and run very well on 25% nitro...

Possible rules if a Club decided to try this...

Class=.28 Outlaw Tunnel

1.Max displacement .28CI

2.No tuned pipes

2.25% nitro max....Race fuel sold by the tank at the pond...

3.Motor claim less carb,pipe and mount..... $100.00.....

Rod, you may have to reduce the size of the fins or it could overcool the engine. I know car/buggy engines are designed to be run under a car body so one of those is made to compensate by having larger fins
