Paul D Posted February 6, 2006 Report Share Posted February 6, 2006 I have a tacho / runtime meter ( with 71 hours registered ) which will show the RPM and clock the runtime for any 4 stroke engine with 3 cylinders. The unit is a small rectangular sealed unit with two wires, one to attach to earth and the other wraps three times around an HT lead. Cost me something like Quote Link to comment Share on other sites More sharing options...
Brian Posted February 19, 2006 Report Share Posted February 19, 2006 Paul If the pickup wire wraps around one of the plug leads, should work on any 4 stroke engine regardless of number of cylinders. Quote Link to comment Share on other sites More sharing options...
Paul D Posted February 19, 2006 Author Report Share Posted February 19, 2006 Brian, It will work as a runtime meter, but my engine apparently has one built in and I dont have any need to measure the runtime now as servicing isn't due for 3 years However, as I now have a 2 stroke it will not read the correct engine RPM ( 2 sparks per rev. as opposed to one ).

alun j. Posted February 19, 2006 Report Share Posted February 19, 2006 Paul, Just a query re. '3 year servicing'....... Do you have to still change things......eg. gear oil, plugs , anodes ?? Alun. Quote Link to comment Share on other sites More sharing options...
Paul D Posted February 19, 2006 Author Report Share Posted February 19, 2006 No gear oil to change ( 2 stroke ) Plugs last 3 years + Shouldnt have to change anodes ( as trailing ). Manual states all that you need to do annually is grease the propellor splines and the fittings ( ie. Tilt mechanism ). Although I intend to drop the gearbox annually or risk the mounting bolts getting stuck. Quote Link to comment Share on other sites More sharing options...
Newboy Posted February 19, 2006 Report Share Posted February 19, 2006 The anode will depend on how much time you spend adrift. If you can see pitted marks on it, change it, it doesn't cost much. Quote Link to comment Share on other sites More sharing options...
alun j. Posted February 19, 2006 Report Share Posted February 19, 2006 Hi Paul, Keep an eye on the anodes; I trail mine and am surprised at how fast they get pitted. Perhaps I'm in and out of the water more than yours........... but mine get changed with each year's service [whether I ak or not !]. Alun.

Paul D Posted February 19, 2006 Author Report Share Posted February 19, 2006 Alun, Yes, come to think about it you have a point as I had to change the anode on the Honda recently as well. The E-Tec doesn't use a trim anode, it has one at the bottom of the leg and another on the engine mount, so I will be keeping an eye on these. Even so, no dealer servicing required for 3 years.

Newboy Posted February 19, 2006 Report Share Posted February 19, 2006 I think you still have to change the impellor annually, Paul. Quote Link to comment Share on other sites More sharing options...
Paul D Posted February 19, 2006 Author Report Share Posted February 19, 2006 I think you still have to change the impellor annually, Paul. Not according to the manual. Three yearly. Quote Link to comment Share on other sites More sharing options...
Coddy Posted February 19, 2006 Report Share Posted February 19, 2006 Interestly enough, when I had my Mariner 4-stroke service last year at Select Marine, he said do not change the plugs on a Mariner/Mercury unless it is really necessary. It seems that the original plugs are of better quality than the replacements and can give problems when you least want them! Coddy Quote Link to comment Share on other sites More sharing options...
Newboy Posted February 20, 2006 Report Share Posted February 20, 2006 Take a spare set out with you, it isn't too hard to change a set of plugs while out unless you are in 6' rollers. If it's anything like cars' they go gradually, so you should see it getting harder to turn over as time goes by. Quote Link to comment Share on other sites More sharing options...
