470 boats and bigger most are using a Tohatsu TLDI 50 HP 35 HP jet power, around 196 #. due to weight and ability to transport. Tohatsu has discontinued it. Cant buy Light weight 2 stokes in the US anymore, EPA rules. And latest is they are probably going to regulate the hi pressure 2 stroke fuel inject models.
http://ambermarine.net/tohatsu_outboards/tohatsu_outboard_35hp_TLDI_Jet.htmlOn my 420 Strella went with the 25 HP Merc 4 stroke Jet Power about 186#, at Bass Pro no one can touch there price here. Heavy, but quiet, and you have to keep power head higher than foot for transport. Uses just under 1 gallon a hr versus 3 plus on a older 30 hp 2 stroke Yamaha I have.
https://www.mercurymarine.com/en/us/engines/outboard/jet/25-40-hp/On the 420 Vega model we have a Mercury 2005 2 stroke 20 HP Jet Power 123 # for it and will test it when ice goes out. Ice is out here on Kauai now!
Any one knows of any 2 stroke 20 HP Mercury Jet Outboards let me know, has to be running as powerheads can,t be rebuilt.
