Paul D Posted December 21, 2005 Author Report Share Posted December 21, 2005 Kam, Yes - I noticed that advantage ( ie. No battery needed ) as well. Also,the charging current available is huge. Found a few posts re: vibration and apparently it improves after running for over 10 hours ( the EMM alters the oil mix after this time ). Even so will not be as smooth as a four cylinder ( or probably 3 cylinder 4 stroke ) when trolling at low revs but not much different ( apparently ). Trolling at low revs is another plus point apparently as well. I found a great review of one ( the 40 HP model as well ) here :- 40 HP E-Tec review Now off to save some money !

Newboy Posted December 22, 2005 Report Share Posted December 22, 2005 In the reviews it says the Etec has a lower trolling speed/rev than TLDi is partly incorrect. The TLDi may have a standard higher trolling/rev, but the TLDi has an unique feature which with a press of the ignition key, it lowers the rev by 50, you can do this 3 times before it returns to 700 rpm.

Dreamcatcher Posted December 29, 2005 Report Share Posted December 29, 2005 Hi Paul, I have a 520 with the Yamaha 30 hp 4 stroke and in the 3 years I have had the boat she has been fantastic. The engine is smooth, quiet and economical. Flat out on a calm day with 2 on board she has achieved 21knts. Normal cruising is 12-16knts. However, at the back of my mind I seem to remeber Orkney stating that the maximum engine rating is 35HP. Might be worth contacting them first just to be on the safe side. Give them a ring on 01243 551456. If you do go for the Yamaha I don't think you will be dissapointed. Cheers, Gary Quote Link to comment Share on other sites More sharing options...
Paul D Posted December 30, 2005 Author Report Share Posted December 30, 2005 Gary, You are correct re: the max engine rating being 35 HP ( it even mentions this on the plate on the boat ). However, I have been told by BHG marine ( who up to 6 months ago were selling 520s with 40HP Yamaha 4 stroke fitted ) that Orkney used to cover these under warranty but have only recently had a change of heart due to liability implications ( ie. They state boat is up to 35 HP and if anything happens with 40 HP engine - why did they cover this under warranty ). Having seen a fair few with 40HP Yamaha 4 strokes fitted, I am going down the 40HP route. My only reservation is the weight of a 40HP E-Tec is actually heavier than the Yamaha - ( not much but still heavier ). I will have a chat with Orkney when they are back after Christmas, to see what they say. cheers Paul Quote Link to comment Share on other sites More sharing options...
Guest Buck Posted January 7, 2006 Report Share Posted January 7, 2006 Me and my brother have been running a 40 E-tec on a orkney fastliner for the last 12 months and found no problems with it,I would have to get speeds and stats off him if you wanted to know.
