chocolate Posted March 9, 2015 Share Posted March 9, 2015 I think the end of year show will be cheaper as they want to get rid of stock. Link to comment Share on other sites More sharing options...

Overdraft Posted March 9, 2015 Share Posted March 9, 2015 If your current motor is running great why are you looking to spend 14-15 k to put a 4 stroke on of the same size? If it's for the fuel economy you will have do be doing a hell of a lot of boating to get your money back. The 4 stroke might also be significantly heavier then your current motor. All moden outboards are good quality. But make sure you find a good dealer that is easily accessible and will back you if you have issues. Link to comment Share on other sites More sharing options...

Overdraft Posted March 9, 2015 Share Posted March 9, 2015 If it's not proped right you could be laboring the engine which will use more fuel. I guess it depends on what you think is a lot. Link to comment Share on other sites More sharing options...
antonywardle Posted March 9, 2015 Share Posted March 9, 2015 How much would you get for your old engine? If its going well, i'd be inclined to keep it until it starts costing you too much money in repairs and servicing. Remember that buy the new engine is only part of it, you have to get the old one off, remove all the gauges and then fit all the new stuff too. Would you be able to reuse the same fuel tank?

fredflathead Posted March 10, 2015 Share Posted March 10, 2015 (edited) I have just put a 90hp Evinrude ETEC on my boat. My old motor was a 115hp Johnson that was 20yrs old we replaced about $500 worth of items to get the motor going (impeller, power pack and thermostat). My brother in law is a marine engineer so the labour cost nothing, I had a heart attack and was in hospital for 4 days so when I got out of hospital we decided to put it in for a service we had it with the problems , they took the head off and found a piston scored that is why it was giving us problems.(We did not want to take the head off) The quote was 20hrs to rebuild and about $4000 in cost. The wife and I decided to replace the motor as we like the hull and it is in good condition, this is now a cost of $12000 and boating for the next 5yrs hopefully. There was a Yamaha for $5000 second hand and anbout 5 yrs old, it meant that I could be in the same situation in about 3yrs. You do have to replace guages, fuel filter and throttle this was included in the price, I ask what would the old motor be worth, it was worth nothing. I am retired and have the money and needed to get rid of some so it worked out ok. I dont drink, smoke and don't spend money silly.I love my boating!!!! I nearly had another heart attack when the wife said go ahead and put on a new motor. norm Edited March 10, 2015 by fredflathead Link to comment Share on other sites More sharing options...
