Cheers Michael,,sounds like a plan,,maybe someone here that has the exact hull and engine set up as you, might give a closer CG
Yeah,,That other 42 inch sounds like the old 90 size sprintcat,,if you can fit a gasser in there,,probably work out,,maybe some extra reinforcing braces around the engine mounts,,as long as you can get the engine back far enough for the CG
I'm glad you're inspired to get your 2 boats running lol,,After thinking about making 2 engine mount positions,it might be tricky to set up the flex shaft and tube,because of the steep shaft angle and engine height,,I measured the CG on my boat,and its 12.5" from transom,and being a 35" boat,makes it 35.7% CG,,maybe a good start point,so maybe instal the engine and shaft,but make it so you can undo/change the engine and shaft position easy,if it doesn't run well,,We had a guy in the club,that ran an 80 OPS engine in a 35" Sprintcat,,same engine position and radio box position as mine,so being a heavier engine,made his CG more nose heavy,but being around 10-15 mph faster than my boat,the extra air speed floated the nose perfectly,,he won races against 90 sized 42" cats,,Just some food for thought as to how the CG can vary depending on speed,weight,trapped air and boat area,aerodynamics
Nice one Dave,Yeah,I can imagine those gas engines weigh a bit,needing to be placed rearward,and also I notice your boat has long horns and shorter tunnel lenght compared to the old Sprincats,putting the CG further back.I get what your saying about corner bog,,cheers
I'm thinking these gas boats being heavy,compared to nitro, need the CG further back.With your 58 ,make the radio box as far back as you can in case you need to go 31-32% as Dave recommends,,happy building lol
