Hi,
I have a 1993 narrow boat powered by a Thorneycroft 27HP, have recently been losing power/dropping out of drive and there is a significant and increasing delay when pushing the throttle forward/back before the drive kicks in (with an audible and felt thump!). Can anyone suggest things I can do before I ask for professional advice on this? (Its already cost me a fortune!!).
Any thoughts gratefully received, including expected life of engine/clutch/gearbox and likely/best replacement and cost.
Thanks - have had a fantastic summer boating by the way
(Boat is a home fit out 1993 V hulled 44ft/6'10" on the mon and brec canal and I purchased this year and have had everything on survey completed (hull/electrics/new exhaust/engine bay clean and serviced engine). There is no rev counter so cant say exactly, however a low tickover in forward drive achieves about 1 mph and middle power about 2/3 mph - haven't gone faster than that as the canal is very shallow.)
