OK it lists a valve clearance check (which I doubt he would actually do) but it seems a lot of money for engine oil and filer and lower leg oil change.
There's a hint of vagueness in there. If he actually does what it says on the tin he'll be down engine oil, gear lube (not cheap), plugs, fuel filter, oil filter, impeller (yearly seems reasonable, but not essential - your call) and I'd guess maybe two hours labour max? The prop deal seems sweet. To keep it in warranty it seems maybe OK but I'd mark up all the consumables with paint and ask for the plugs and impeller (c/w woodruff key) as spares. Allow that a mech needs £40 plus VAT an hour to stay in business....

SDDave's guy is looking for £223-20 to do his over the top service. The full service kit plus oil come to £82 so he's after £141-20 labour... too much I reckon.

If he did it by the book without plugs or impeller then parts/oil would only be £35 so I'd be thinking about the price my dealer quoted... around £100 inc vat.

Thanks for your comments.
Glad to know I've not picked up a duff engine. I agree it's not really worth worrying about, but I think I wasn't expecting any vibration at all. I think I do too much pottering, as I agree that it smooths out. That's perhaps why not noticed on the 6hp, as it probably got more of a workout. I guess I was thinking bigger = smoother, but it sounds as though we need to get to 3 or more cylinders before that becomes true ? Anyhow, all fine - it's basically a lovely engine
Not sure what pitch my prop is - maybe I can measure this ? Will then just generally monitor for a bit, as too much pottering again means no conclusive findings yet ! but looking like... occasional ventilation - and when fairly well loaded.

Pitch is printed on the back of one prop blade.

I think the vibration is worse to some extent with the larger moving mass of the engine internals on the 20 vs the 6. As Jeff says the 25 has the offset crank starting to smooth out the mechanical imbalance... as well as the smoother power pulses of 3cyls.

Suzuki DF20AES - prop size

Dave,
Re servicing costs, I've had three annual services all at around £120 each. Bought my motor in the autumn so was over 6 months old when it went in for its first service with 18hrs on the clock. The dealer combined this with an annual service at no extra cost.
Thanks for info on your Ribeye spec. I also contacted them re conflicting info on the TS400. Website stated max 20hp and 92kg max weight, while brochure says 30hp but only 59kg weight. They were adamant 20hp max was correct and I noticed the weight on the website has now been reduced to 55kg. Seems rather low for a 4m rib to me, albeit a very light one. Shame as they seem nice boats. Considering the Highfield CL380 now instead.

Seems then with Jeffs £65+vat, your £120 and my dealers quoting around £100... then £100 give or take is where it ought to be and the £200+ guys are "avin a larf".

Ok I'll ring around then. Thanks.

So today I'm gonna order my new prop. Several folk selling them but nobody listing a nut kit. Not worth having a spare prop without a spare nut and I can't see one anywhere for the DF 20?

Cheers

Btw, I think ribeye and Highfield have their bottoms made by the same Chinese manufacturer. They set them up adjacent to each other at the Southampton show a few years back and the similarities were uncanny.

Also, can I have a dealer name for who's providing these £100 services? If the time and place is right I could incorporate it into a weekend away some time soon.

Ta.

>>>Not worth having a spare prop without a spare nut

Agreed. It was easy with my old Mercury 15 as that was a nyloc nut and a size I had to hand in my misc spares. The Suzuki has a very fine thread and didn't match anything I had.


So I've just received my prop nut, washer and split pin from Sands Marine... about the only folks I could find with them listed and in stock... boat sales,Watersports,Sailing Equipment,outboard finance,kayaks,Inflatables,Electronics

My "about £100 for a yearly service" dealer is probably nowhere you'd visit but its Ely Chandlers, Cambridgeshire...

Mmm so you elected not to get the stopper. I agree that the risk of loosing that to Davey Jones' is much slimmer than the other parts, prop included and given what they're charging for it I can understand the gamble but once the prop is off there is nothing to keep the stopper on. It's all insurance at the end of the day, but if you had to fit a spare prop with the stopper missing I assume the prop would hit the gearbox housing?

My heart and wallet are conflicted over this one!

Cheers
