New(used) bf 50

[Markham]

I just purchased a bf 50, 1996 for $2,800 Can. I hope it wasn't too much but time will tell.It is to replace a 1996 Johnson 60 that was a victim of oil injection technology starvation to the top cylinder. Need less to say a rebuild is out of the question.I am hoping for good things from the BF 50 as I have a great result with it's little brother, a BF 15 from last year, another replacement for an aging Johnson 25.I have a number of questions. The bf50 looks and sounds great(tank tersted only) and I am really going on my limited intuition here. I will run it on a K.M.V. 4.8 metre. Believe it or not the motor spent it's first years working on a weed harvesting barge. How should I approach the "breack in" period? Can my steering and O.M.C. control box be cobbled together to save some bucks? What is my johnson 60 bottom end worth with power trim, tilt and all the other goodies from the powerhead? should I sell them pieced out or as a unit? Thanks for any assistance, I just need to put this all behind me and get on the water. Mark

Re: New(used) bf 50

You are buying a used engine so break in is not an issue.You will need to prop it to your needs as you are certainly not running a barge.Steering should be no problem if you were through the tilt tube previous.Controls wo'nt work.Value of the old engine is subjective.You indicate it is not rebuildable.Why?

Re: New(used) bf 50

Thanks Hondon for the reply. I admit to a little tongue in cheek about the breacking in period although I would admit to being a little cautious about over doing it at full throttle for a motor that has been probably lugged around the lake collecting weeds. I will let you know about the performance after this weekend. The re-building of the 60 Johnson seemed to be out of the question because the list was growing past the 50% cost of new replacement threshold that I have heard about.I bored out the block by 20,000 as the only kit from O.M.C. warranted that number. After costing three pistons, rings, bearings, one rod, gaskets etc., the last straw was the re chroming of the crank or replacement at $800.00( as the crank appears to be pitted owing to it's moon lighting as a salt water motor) which suggested I put it on the back of the bench for the time being and do it myself this winter.I had considered selling it off( lower unit) to try and defray the cost of the BF 50.I am looking forward to this week end and running the BF I hope I can get everything together in time to play.

Re: New(used) bf 50

I ran the BF50 for the first time this week end and can make a report. Any assistance would be appreciated. I used the prop that came with the motor, a10 and 5/8 x 12. The boat wouldn't plane with me alone on my KMV 4.8m but would with a 200lb friend in the bow. The tach redlined an ran full out at 6,200 RPM. Managed to secure a Merc. prop, 11x14 that got out of the hole, albeit slowly, and gave me a better turn of speed at 5,500 RPM which I think is the suggested rev's.Could the boat climb out of the hole quicker if the motor was elevated a couple of inches? How critical is "too low"? I noticed on each occassion I ran the boat a lot of clean oil was running out of the lower housing under the main cowling. Checking the oil level frequently showed no signs of oil loss. Is it possibly spilled oil from a change or from winterizing. What is the recomended prop size and RPM?Mark

Hey Markham, I just purchased a BF50 and am also mounting it to a KMV 480cc. I will be mounting it myself so any hints you can give me would be appreciated. I also live in Toronto.<br />Cheers,<br />Don
