1999 Yam Saltwater Series 250s... After 700+ hours, I started having a problem where the oil tank on the side of the engine was not filling and the alarm was sounding. I figured out it's a filter in the tank in the bilge (and not the pump, and not the float switches inside the tank). I...

I have a 6 year old Simrad cx-44, and an airmar b-260 (dual frequency) 1000w transducer. 2 Years ago my 50kHz display started behaving very (no VERRRY) poorly . Weak signal. Could not even read bottom at 30 feet. So of course that is completely unacceptable. I opted to stop using the 50 and...

It has not happend since adjusting the wiring harness underneath the plastic cover, and applying electrical tape. Pretty sure it was a short. Did have another interesting problem this weekend though. Topic for another thread. Ed

Well I may have found it. Got down there tonight after work just in time to get eaten alive by the midgies. I have a very very very strong hunch that it was as Clyde said...caused by a short in the wires. I did as he recommended and walked back along the pink wires which quickly be came...

Hi - Tom. Thanks. So are you saying the winky gets inserted in line into one of those connections, so both connections of the winky are used connecting to 2 pieces that would otherwise be connected to each other? In any case I don't think it provides much value in this case, since its an...

alarm sounds when cold, without engine running. tstat & poppit ok/new

I guess I could swap them to the other engine one by one and see if the problem follows the parts. I have twin 250s. Problem only occurs on one engine. Ed

Un-bah-lievable....new problem OK for those that don't remember 3 postings ago... 1999 ox66 250hp Cold engine Alarm sounding & thermal indicator flashing with key in on position with engine off. Thermal indicator on the instrument panel flashing next to the 3 oil indicators. Turn engine on...

Problem solved. 3 LP Fuel Pumps - orginal recipe. 12 years old. Amen...

First - thanks for such a detailed response. Very much appreciated.

Finally put the boat in the water after replacing the lower unit - ugh... Think of the money I'm saving by not driving it... Trying to get out of the hole it stalls (around 1500-2000 RPM), starts right back up again, but can't get obove 2K under load. Figure I'll disconnect the LPs and check...

Brought it into BM. Bearings Shot. Broken gear(s) The result of sitting in salted water over the winter. Bearing couldn't handle it during the flushing process. A few times while running it I noticed it sputter. Likely the result of eating gears. Replacing the lower unit - it's only money...

Yeah -point taken. Will be calling BM tomorrow.

So no mechanic on duty today at Baert, so need to call tomorrow. I also called Port Harbor Marine in Portland. The guy I talked to there said they have a 50/50 success in pulling the housing. When it doesn't work, it usually means the housing gets cracked. So some additional searching on this...

OK - where do I begin? With my conclusion or the advice I need???? Here's the short/long of it : Filled with fresh gear oil Run for 15 minutes at ~1200 RPM - 15 mins Drain Repeated 4 times Each time the oil got cleaner and cleaner. You would actualy think it was as good as what went in after...

Guys - Thanks..I really appreciate the feedback thus far. Unfortunately she's a big girl (30' grady CC) So it will require me to have the marina put it in, once I get the LU cleaned out. Once in the water, it's in until the fall unless I pay extra to yank it. In York Harbor, we do have spot...

Thanks for the advice. Will report back after the weekend. It was definitely not swapped plugs. The magnetic one was on bottom, but that one did not have the plastic washer on it, so that may be the source of the leak. There was a very minor metal dust on the plug tip. More so than the...

A little advice please - especially if you had this problem and have cured it. 1999 Yam 250HP Saltwater Series Every spring before launch, I have changed gear fluid. This year while draining into a funnel and into a plastic 1 gallon bucket, I noticed my port engine was draining very slowly...

OK I'll answer my self... Had some success today.... Here's what you need to do (what I did) Raised the engine heated the shaft (on the under side of engine) from slighly above the grease fitting all the way up to where the top bearing (about a foot long). Heating this up in 55 degree...

Hi Boys - I searched on this, but could not find. If it's already been discussed a reference link would be appreciated. Anyway, 1999 Yam 250 OX66. Trying to grease the vertical steering column (page 7-28 in the manual) aka the swivel bracket assembly. Here's the trouble. I can get grease to...
