I presently have a 83 2 stroke Evinrude 40hp engine on the rear of a 4.3 meter aluminium runablut used for fishing / crabbing and a bit of kid fun running around etc.<br /><br />I am looking at replacing with a 4 stroke of similar power. SAlt water use<br /><br />Can anyone advise the best solution for a a fit. Considerations presubably are weight, power, speed, cost, fuel consumption, reliability brand etc.<br /><br />Look forward toi your suggestions<br /><br />Mike

Re: 4 Stroke OB best for me?

I never talked to a 4 stroke owner who wanted to go back to a 2 stroke, Mike, so I think that part is a no-brainer. Many claim that they don't want to go to a 4 stroke, but I never heard anyone wanting to go back.<br /><br />As to what 4 stroke, only Mercury and Johnson-Suzuki offer EFI 4 strokes in that power range. I strongly recommend EFI.<br /><br />Good luck. :)

Re: 4 Stroke OB best for me?

Mike,<br />I strongly agree with JB that EFI is the way to go in a 4 stroke!<br />The next big decider has to be service and therefore you need to look which manufacture has the best support in your area of Indonesia.<br />Mercury has a 30 and 40 HP EFI 3 cylinder that has a dry weight of 216 lbs, (approx 230 lbs installed).<br />Johnson does not sell anything less than 90 HP in EFI which I think would be way too big for your boat! <br />Suzuki has a 40 and 50 HP EFI (I can’t find the weight) but their 30 HP is not EFI.<br />I’m not qualified to say if these engines would be too heavy for your boat, but I do know they run very smoothly and you would be pleased with the performance and fuel economy.

JB.....I was not aware that they made carbed 4 stroke outboards. I would have to agree with you about the EFI, seems that EFI would just be easier on a 4 stroke outboard.

Re: 4 Stroke OB best for me?

Forgive my unashamed American pride, but my "obsolete" American made Bearcat 55 HP 4 stroke outboard, the final name for the 1960 Homelite 4 stroke 55, weighs in at 227 lbs. Why is it that the current manufacturers have had such trouble bringing their 4 stroke's weight down? I know Honda bought a few Homelite/Bearcat motors to analyze while they were trying to design their early 4 stroke motors. Honda is making a great big deal out of their BF50 weighing in at only 212 lbs. What am I missing? They do have a nice motor, but don't you think they could have acheived that weight savings of 15 lbs in a lot less than 43 years? Actually it took them a very long time to just catch up to the earlier American competition, which was then a still and silent target. Too bad Fisher Pierce threw in the towel on their motors when they did. Had they waited another year (fuel crisis) they'd have become leader of the field. Don't get me wrong, I admire Honda and Japanese engineering. I just feel a little smug that we did it first. I guess they get to feel smug that they are the ones still doing it.

I believe the Homelite Bearcat HP was rated at the flywheel and the Honda is rated at the prop which makes the bearcat something less than 55 hp. I wonder, did it also have power tilt and trim which would add a few pounds if it didn't. My memory of my friends bearcat was that it was a slug dog in terms of speed. I'm guessing that a head to head comparison of the Homelite and a modern Yamaha, Honda, or Suzuki would be a no brainer.

Say, BP.<br /><br />I agree that Lou Fageol was forty years ahead of his time when he adapted the Crosley auto engine to outboard use. That engine evolved to the Homelite 55 engine, which became the Bearcat 55 when Fisher Pierce bought it from Homelite.<br /><br />My memories of the engine are dominated by it's smoothness and quietness, and the fact that my friend could cruise all day on much less fuel than the 50hp. 2 stroke locomotives of the day.<br /><br />Unfortunately, it is just as obsolete as they (the old 2 strokes) are. No matter. It is still a great engine and still does a fine job.

Re: 4 Stroke OB best for me?

Jimd, I'm sure the current 50's would perform a tad better than my Bearcat, and I can't say from experience yet just how it will run my boat. The propoganda of the day tried to compare it to a Merc 75 (also flywheel rated). The idea was the torque of the Homelite/Bearcat could get on a plane in a hurry and do everything the Merc could (except about 3-4 mph slower in top speed) on less than half the fuel. There were two identical hulls in the comparison. Doesn't guarantee they were tuned 100% identical, or that the same result would be had with a different sort of hull. But it was a great motor, and as carbed 4 strokes go not really all that far behind anyway. Naturally any new whiz-bang injected motor ought to do more with the fuel it drinks. I like this motor because of it being inexpensive to own and operate compared to any new motor, simple, and nostalgic. It fits in with the age of my old Silver Line hull. No, mine does not have tilt and trim, but neither does the Honda at that listed weight. My point is not that the Bearcat is better, it is that the best of todays motors are not AS much better as one might expect given the additional 43 years to develop the technology. That, and that once in the great while great ideas aren't always given all the attention they deserve because we get set in our ways. JB is right Lou Fageol was way ahead of his time. There is a very small group of us who are carrying the torch for these motors. Not sure yet but it seems like they may be getting a little more in demand. There are a few who have a passion for restoring these. At any rate we have lots of relatively inexpensive fun messing with them and running them.

Re: 4 Stroke OB best for me?

The boat is actually in Bundaberg Australia and will be used there while my family and I return for holidays periodically.<br /><br />It therefore seems that if EFI is desireable, and from my point of view PTT is a must, based on serviceability and availablity the selection should go to Mercury or Suzuki if honda and others dont have a comparable 40hp model in the weight & configuration needed unless someone else can advise on this aspect.<br /><br />Are the Suzi's, Mercs and Hoda all now rated at the prop also?<br /><br />Does anyone know the weight of my old '83 40 hp Evinrude with PTT?

Re: 4 Stroke OB best for me?

Further to my earlier post, does anyone have any feedback to offer in regards to Tohatsu motors.<br /><br />What is their performance and reliability and stage of technical advancement and development like?<br /><br />Would it be a rival for the already suggested motors in this post with EFI, PTT, remote controls, weight light and price competetive?

Don't totally ignore the 2-strokes. The Tohatsu TLDI makes a DFI based on orbital direct fuel injection. Totahatsu's and Nissan's have a great reputation for reliability. Did anyone say E-Tec? Look at this engine from Bomb too.
