| I found all the specs of the engine i am using so the engine weight 390 g and two electric motors would nearly twice this weight plus the batterys weight aswell i would have more weight if i use two electric motors and batterys than if i used the engine and other things i will be using in the installation
PRO-21BXS Specifications

Bore (mm/in.) 16.6/0.654
Stroke (mm/in.) 16.0/0.630
Practical RPM 3000~38000
Output (BHP/RPM) 2.1/30000
Weight (oz.g) 13.76/390
i know this engine has alot more rpm and bhp than most marine engines but it's cheaper than buying another engine to put in, i have most of the thing i need i have the engine,fuel tank,controls,propeller, coupling,and all i have to get is the propshafts ,coolinghead,clutch,spurgears,rudders,and some other things i need so it is cheaper than fitting another engine in or fitting two electric motors in. |
