Just came across this thread from 2009 - nothing new under the sun, eh!

There's wisdom for you I've learned a lot today. Thank you. And now it seems I am an "engager" on this forum. So not a total loss 😇

The RCR guy was diamond - no complaints there.

As I now appreciate - still mind blown that this looks like the explanation! Leaves on the prop - who would have thought it. At least I didn't fork out £235 RCR sub + £150 call out fee or anything expensive like that to find out via this forum about this common autumn phenomenon 🤦‍♂️

So the leaves get stuck on the prop you can see in this pic? Hard to believe it can make such a difference. Not doubting, just surprised!

No difference to speed of the prop shaft - it carries on at normal speed

Ok, sounds like I having to work with for next time. Thanks everyone (this forum is awesome) 👍

No, revs stay the same. Don't know what kind of gearbox it is but. here's a photo. Oil level is ok. That would make sense in as much as I've been out twice in the summer and had no issue. Is it really a common problem then? My boat pretty much stopped moving forward at one point. Can't believe it could be something as simple as that - not a wind up (leaves on the line etc

Hi, This may not be the correct forum to discuss but as my nb has a BMC engine I thought I'd post it here. I have a recurring issue with foreword thrust (recurring because it also happened last year). Boat is fine when I start out but after about 30 mins, speed drops until barely any forward movement. Reverse thrust is good. When I stick it in reverse and crank up the revs, when I put it back in foreword it regains thrust. But it drops down again after 15-20 mins. If I switch off the engine and leave it for a while, when I start up again, foreword is fine. But then drops off again. Things to note: 1. weed hatch is clear 2. RCR engineer has been out to check it. As it was over night, engine had totally cooled down etc and engineer couldn't find anything wrong - foreword and reverse thrust strong. 3. RCR engineer checked and slightly adjusted the cable; 4. RCR engineer checked gearbox oil - right amount in there just dirty. Gearbox was replaced in May this year by qualified engineer. So we carried on but same problem has recurred. Just wondering if anyone has had a similar experience? Thanks Andrew

Thank you @Tonka @David Mack!

I'm looking to replace my hatch/cabin cover. It is wooden with an aluminium top and not very secure. I am currently moored in Tamworth. Does anyone know of a Midlands-based company or individual who could fabricate a metal replacement? Thanks Andrew

Thanks for all your replies. Engine is being checked over by a qualified mechanic; filters changed and spares acquired ?

Thanks for replying. No, it's a late 1980s boat and the engine is in pretty good condition, I think. The previous owner traveled a lot but I've not taken it out except to be blacked.
