help with prop/misc

[auto]

Hi! I have a 16 ft F/G boat with a 1974 merc 70 hp, I currently have a 12" prop, it seems quite sluggish from the start, but gets better once the boat plains out. Should I have a different pitch of prop? I don't know the rpm, as I don't have a gauge. However it doesn't seem to be running at a very high rpm.<br /><br />Also how difficult (connections) would it be to install a tach & would an automotive one work?<br /><br />thanks!

Re: help with prop/misc

It is really important to know more about your boat and setup to offer good advice.<br /><br />Boat design, hull, weight (laden), overall shape and, most important, your rpm at wot.<br /><br />Do not use automotive gear on your boat. Won't last, won't work, won't meet safety specs. (yes, agrred there may be a few exceptions, but...)<br /><br />Check www.tinytach.com for an unexpensive solution.
