Hey guys!

I've got a 2001 Johnson 250 on the back of my 225 which at one point pushed it along at about 42 mph and started right up every time. About a month ago I ran the boat out in the Ocean for about a 45min run (Haulover inlet to Stiltsville in Miami) at about 3/4 throttle and occasional WOT seas permitting... I noticed some engine surging and reluctance to go beyond 3/4 throttle so I backed off a bit... :504_shrugging: Thought maybe some fuel filter restriction or something since I don't know when the last engine service was completed being that I bought the boat last November. Then we idled and did some runs back to the sandbar via the IWC in Miami. I had trouble re-starting the engine upon leaving the sandbar and was somewhat embarrassed at the plume of smoke it made once started. Long story short, I figured I need to get this thing properly serviced so I did some searching and came up a with a nearby marine repair shop that works on Johnsons (we're in Mercury - Yamaha territory) so I made the appointment, and left a squawk sheet:

Engine surging at top end...
Burning excessive oil (1.5 gal. on that last 1hr 45min run) and smoking after warm-up...
No charge indicated on ammeter...
Engine trim sticking intermittently...

$2655 later the boat was ready! sSa_cry4 $1955 in parts and tax alone... sSc_eek The rest labor.
They went through the repair with me and showed me the bad parts...
The fuel pump (VRO) that also pumps oil was shot (holes in the diaphragm) which most likely caused the engine surging and excessive oil burn ($583). The magnets had detached from the flywheel and was destroying the stator ($413). The voltage regulator was shot ($292)... Well you get the message... A laundry list of issues any of which would have eventually stranded me if not ruined the engine. The thermostats were stuck as well... One full open one barely open...

So I'm hoping that this old Johnson will not give me any trouble for the foreseeable future. I don't care if it burns more gas and oil than a modern 250 outboard... I just want it to run good and reliably.

Thanks for reading my rant! :605_thumbs_up:

I feel your pain, everything you stated I've gone through in the last two years, actually I just had to replace my vro again, got a year out of it before problems, the original wasn't pumping fuel, the replacement, started pumping quadruple oil.

Hang in there bud, these old girls need some extra love from time to time but the only other option is a repower and then we're really talking $

Thermostats are often overlooked by new owners. That is why I tell anyone that gets a new to them used motor, service EVERYTHING. That includes, fuel filters, spark plugs, water pump, lower unit oil, thermostats, and pop off valves to name a few. Rebuilding the carbs is a good idea too unless you know when they were done last and the boat hasn't been sitting or running stale fuel. I have heard of the flywheel shedding magnets.

At least you should be in good shape for a while.... and remember BOAT = Break Out Another Thousand , Bring Over Another Thousand, or Bankruptcy On a Trailer!

Thanks for your sympathy guys... This boat was not well maintained despite being garage kept and run primarily up and down the St Johns river by its last owner... The mechs traced the last service back to 2013, but there were issues that piled up over time and disregarded... Overall I've got about $20K invested including the trailer, so I figure I'm still ahead of the game... I plan on doing some trolling for Mahi down in the Keys this summer so I'm glad I didn't just jiffy-lube it.

X2 on Wingtime's comments, I had the same laundry list across the last two years I owned my looper right down to the thrown magnets and ruined stator

Wow... Looks like while this engine may have a good basic block and lower unit it's not the most trouble free motor out there... Then again, it's 16 years old. Maybe upgrade to a used/rebuilt ETec down the road... I can't see spending the money for a new engine...

The only issue I had with my Ocean Pro was a power pack. They are reliable motors that will get you home if you treat em right. Parts are readily availible and are resonably priced. Of course they are thirsty.

A Etec will be a direct bolt on to your existing rigging and will save you 30%+ fuel burn.

I will say one thing about these motors, I bought mine new in 97 and never had a single problem the first 16 years, I would buy it again.
