just a heads up for the  guys that use a  suzuki   Df  from 90 hp     to the   140 HP    should you engine  cut out at idle   chances are its the Idle control valve sticking  or its  U/s     you could  try  cleaning it   using brake cleaner   or you  could fit a new one   Suzuki  prices  are around the £400 .8p    plus  £6.   ?  plus the gasket    well after having  trouble with my engine  cutting out at  tick over   ( Idle )   no fault codes showing up    i was scratching my  head a little    so i looked on a few  forums   and came across  a  few guys who have had the same problem   the Fix is to  buy a  Mk1  ford  KA  1996  to 2008    Focus   or  Galaxy     part no  9F715-AA  you have to  cut the old  plug off   and buy one off Ebay  that fits the   KA   Galaxy & focus   Idle control valve  total cost    £35      quite a  saving    and you can get then off ebay with a 5  year guarantee   Tight lines  Alain

My 2014 suzuki 140 had plenty of other issues but not that one. Regular issues of not going above 3000rpm, gear bearings, power trim constant failings etc etc. Sold at 350hrs, since heard the new owner is having other issues with it. For the record it had had 8 annual services by Suzuki in those 350hrs.

Hopefully you've got the E10 out of it, its hydrophilic which attracts water and boats tend to be left long periods without use where there's more chance of water building up. Also keep a close eye on those powerhead anodes and replace them when needed. Ive always struggled to get 12 months use from my anodes on Suzuki's. Some people leave the anodes to 100hr services, however many people don't do 100hrs of engine running in a year so they need checking.

Also the plugs normally need replacing at 100hrs or sooner quite often. 100 quid per hour is crazy, the most expensive here would be half that but I only pay around 25 per hour for a mobile marine mechanic to do the work at my home. Either he can supple the service kits or I can get them, he gets them far cheaper than I can, so I leave it all to him. His family used to own a Yamaha dealership and his brother owns one of the biggest Suzuki deanships in our state, so they both have the best reputations for mechanical work from servicing to complete rebuilds. I do get a reduced rate as I often skipper the mechanics commercial boat, which is another more lucrative business for him.

Cheers for the heads up on the Anodes    i always carry a  service kit will me       the  £100  per hour  is plus  VAT  @ 20%    so its £120  per hour      usually 4  hours to service the engine plus  the  service kit  or parts required  if not in the kit        thats why i  do it myself        tight lines Alain

4 hours for a service? Is that a major service or just a lube job? 
It sounds like a long time to me, especially if you’re in the business and you have all the correct tools and equipment to hand.

£100 per hour is fair enough for any skilled worker with tools. I was surprised that it could take 4 hours though. It’s not like they actually change anything they just show you some old worn it parts that they found somewhere else completely and do a bit of tooth whistling. Bit like heating engineers do.
