View Full Version : New motor for Sanity

24-03-2007, 09:31 PM
Hi to you all , after years of top service it is time ti replace the outboard . sanity is 5.5 half cab with a fair bit a weight , all up ready for a three day trip outside around 850 to 950 Kg . At the moment she has a 115 johnson 1976 V4 . she runs at 12 to 16 ltr an hour

What would be a good motor for her , she dry stable and sound fiber glass hull .

Pogo your current engine is flywheel HP rated so has approx the same get up and go as a more modern 90hp 2 stroke 4cylinder (say 85model onwards), if you buy these more modern carb or EFI 115s you will be happy with the extra get up and go but based on your fuel figures you will use a fair bit more fuel, a modern high tech engine either dfi 2st or 4st in 115hp will bring you closer to the same economy but the 4st will have around the same performance as your old engine.
It's a juggling act and depends I guess how happy you were with that good old girl.

cheers fnq

FNQCairns , thanks I am swayed toward the 4st V and was not sure of the rating differance for the prop and flywheel , the fuel usage is for good days and depending on the load fuel can go as high as 20 ltr an hour .
I am not sure if I will get a new , or a used .

It sounds like your motor is the cousin of my '76 115Hp Evinrude.

My tilt/trim is playing up, and rather than throw good money after bad - I think I will go the new motor route.

Perhaps we can start a new artificial reef with the old OMCs.

I need something a bit lighter too, as my boat sags in the bum a bit with 115HP, twin batteries, fuel tanks etc, all down at the business end of the boat.

Especially as the hull is only rated to 85 Hp.

Ahhh, the joys of buying a second-hand boat.

:D Thanks to you alll , maby a bit of sweet talking over the next few weeks to the one that is !! ,
sea dog , that is the way mine started about 6 months ago i was able to repair the electrics my self but now it is starting to poll the quote for a ner motor for the tilt and trim was 700 , so as you said good after bad is not the go , now the gearbox has a seal starting to go and the controls are not the best , but at this age realy can't complane .

thanks to you all pogobill .:D

kind of thinking a 140HP 4 stroke may be a tad on the heavy side (maybe)
