Known problems with Yamaha 30??

[Andy JC]

I've just bought a 1998 Yamaha 30GMS (2 smoke, 2cyl) which appears to be in pretty good nick.
Although it was described as 'serviced' by the dealer I'm not sure how thoroughly this was done and I'm going to give it a service myself for peace of mind. Due to the fact that my young daughters come out on the water with me and I'd rather not take any chances as far as reliability is concerned.
I've got some new plugs, gear oil and also intend to check the usual service areas (grease points, fuel filter etc.) but would like to know if there are any 'known problems' with this model of engine and if there's anything I should look out for or pay particular attention to.
It doesn't look like it's had a particularly hard life so fingers crossed it's been a good buy but can anybody offer an opinion or any advice on this particular model?
Thanks

Andy

it's a good moda, check the water pump in it, and you should be all set.

Thanks Fred. When you say water pump I presume you're refering to the impeller?

The lack of replies to this thread illustrates how reliable Yamaha 2 strokes are, no doubt one of the market leaders. Andy if your really worried you could check the compression, believe there needs to be no more than a 10-15% difference between each cylinder but don't quote me on that because I have never done it.
Impeller is probably worth replacing and make sure the fuel tank is nice and clean as bits of crap can block the jets in the carbs on these engines, no idea how they get past the filter! Might be worth buying a clymer manual for your engine very helpful for DIY servicing.

Will check the compression and was going to do the impeller for piece of mind.

Came supplied with a brand new fuel tank so no worries there

Nice to know it's a decent engine, cheers ADS!

Hi

I have a Yam 30d PTT on my Avon although i have only owned it for about a year, its a 1999/2000 model and had 15 hours on from new when i bought it last year,

i had it serviced in feb this year at my local yam dealer no problems didnt need new water pump

it has never missed beat and it took a real hammer last year out nearly every weekend from may-oct and 4 week holiday use i reackon i put about 150 hours on it and an outing in Jan over to Anglesey

it is a great little engine it pushes my Avon along a treat at the weekend i had 4 adults 2 kids and a 3rd 10 year old on a wakeboard behind at the same time and still touched 22mph !!

although weight distribution was crucial to getting on the Plane !

Cheers for that floater


Took it for a blast last weekend down at Weymouth, GPS was reading 35mph - felt pretty darn fast in a sib

Very please with it, ran sweetly all day!
