Various prop advice please
I want to build some boats to take out baited fishing lines a few hundred yards to sea and drop them or use the boat for trolling fishing lures (still attached to shore by line). I will be in the Azores Islands.
I have various .12 -.15 marine and car nitro engines to be run on methanol/castor mix without nitro (too difficult to ship out here). and also various weedcutter engines of 23-26cc ready for converting to aero or boat (have engineering machinery)
Problem is that as an aero man I have no idea about boat props!
Could someone please suggest some props for the small nitros run on straight fuel and also for the weedcutter engines? Speed is not important but reliability, towing power and duration are.
