As above wanted to know what revs me honda outboard was doing
so i bought one of these bad boys for 20 squid they work a treat .
battery last for 3-5 years .
easy to fit one wire to any earth on engine other wire wrapes round the ht lead to pick up pulses off the spark , realy easy .
The earth lead -
the ht lead pick up wrapped 4 times real easy -
The readings -
15mph reading .
Flat out 28mph - 6342 rpm .
The unit also has a service reminder and an hour counter which can both be
reset if you want to .
The info means i could if i wanted change the prop from a 10 pitch to a 12
and gain some economy and performance.
hope this is of some use to you lot .
:yltype: thanks for reading
