Check out Toy-Jets water pump adapter and motor mounts. I like the fact that he doesn't use an engine cradle. More room down there without the cradle. The water pump adapter gives a bit more room and is neater then using that extra hose. Single line in/out on his water pump. Nice and neat. RH is great but Toy-Jet is very inovative. I now understand why his rear wing/radiator works. I shall be upgrading my wing in the future to his new wing design....
