"Hi I have a 22ft tug running
"Hi I have a 22ft tug running a twin cyclinder Volvo penta 2002 workboat setup. Please see my attempt at a
website ( under construction so contact links don't work at the moment ) and check the first page for pic of the engine and trans.
http://plan9.flemingc.on.ca/~damicamp/index.html The engine runs perfect and cold starts are not an issue
( good charge in batteries ). The engine runs cleanly up to around 2900rpm and idles fine. Recently I have
been having an issue with the transmission - or at least I think its the trans. Scenario..... If I start
the boat from cold the engine will fire and run as normal with full revs at hand in neutral. I let the
engine warm to normal temp. If I then engage drive - forward or reverse - it will not rev. If I apply full
throttle in either direction it will sit without the revs increasing. Now at this point I should say that
there is no obstruction to the prop as I can turn the drive shaft very easily by hand, and when I engage
either gear it does so perfectly and the shaft will rotate. So, there it will sit just wanting to rev but
not going anywhere. Now after about five mins or so attempting to get some forward or reverse motion the
revs will gradually creap up when in gear and then you will have full throttle in whichever direction you
were attempting to use. So I then move the shifter to the opposite direction expecting to have full
throttle but no, you will have to wait until the revs increase in that gear also ( maybe another 5 mins ).
But once you have got motion for the first time in either direction it will be on tap straight away ANY
time after that, its like it takes mins to get revs the first time but after that no problem for as long as
you are running. A few months ago when I put the boat in the water I had full throttle on demand straight
off the trailer with a cold engine. When you have drive it will work all day as if there are no problems,
and is 100 % reliable. This problem seems to be getting worse and only happens after the boat has been
unused for maybe 24 hrs or less? Any help or guidence would be greatly appreciated.
Thanks.
