idolz Posted May 31, 2010 Share Posted May 31, 2010 Does anybody know much about upgrading a 2005 EVINRUDE 135Hp DI to a 150hp as they are both the same Cubic capacity,, and the same engine apparently???? Link to comment Share on other sites More sharing options...
slinkymalinky Posted May 31, 2010 Share Posted May 31, 2010 Send a pm to huey at Hewitt Marine. They're Evinrude dealers and what huey (Craig) doesn't know about them, isn't worth knowing. Craig's full details are here! Cheers, Slinky Link to comment Share on other sites More sharing options...
a boat Posted May 31, 2010 Share Posted May 31, 2010 Hi, yes you are correct they are the same block with a different "brain" or more correctly different software versions. It is an often asked question with all clean tech engines due to all brands basically reprogramming the EMM/ECU to produce more HP. If you were smart enough you could reprogram an engine but you would need to proper hardware and skills to do it and here in Oz there is no company I know of that can do this. In the States, where they sell ALOT more outboards and there is a big enough market to make it worth while for a company to set themselves up like this there a massive fines due to the EPA and changing emissions on clean engine. With the old tech engines like carby engines of both 2 and 4 strokes it was easy and cheap to make more power if you had the small brother of a family. If you are after more performance better off to make sure she is set-up and propped right and I hope you are seeing about 5000-5250 at WOT otherwise you are propped or set-up wrong. Cheers, Huey.

Could you just buy a new ECU for it ?????, no idea what the cost for this would be ?? or is there more than just the ECU ??? Link to comment Share on other sites More sharing options...
a boat Posted June 1, 2010 Share Posted June 1, 2010 (edited) Could you just buy a new ECU for it ?????, no idea what the cost for this would be ?? or is there more than just the ECU ??? Yes you could but I would spend that money on making sure she is set-up and propped right before going down that path. Here in Oz there are no fines so it is upto the owner, but if you ever need to replace an ECU or EMM they come without any info inside them and before they get shipped the manufacturer supplies the info relating to the engine it is going to go on. Yes you could get around this by buying a second hand 150HP ECU and fitting but again I would spend my money elsewhere. Cheers, Huey.

idolz Posted June 2, 2010 Author Share Posted June 2, 2010 i bought the boat with a motor that has no compression on one of the cylinders,,, (EVINRUDE 2005 model 135 DI)....i was thinking of just buying a new motor,,,,, but i assume the cost of a full rebuild would be around the 2-4K mark,,, i would be happy to throw in another Grand to have it upgraded to a 150hp while it was being repaired Anthony Link to comment Share on other sites More sharing options...

To rebuild, depending on what caused the failure and I would not mind betting fuel related due to small lines, wrong filteres and/or wrong prop, would cost about about $4-$5K done right and that is assuming no dmages to crankshaft,con-rods, bearings etc. For only $2K you will get nothing like what you want. Your call but I hope you paid the right money for the rig and consiering a new clean tech 150HP engine of any brand is around $19K upwards it is a lot cheaper to rebuild this engine, but you need to make sure the root casue is found otherwise chances are it can and will happen again.
