Just by the way, this may also explain away why, when fully trimmed into the transom the motors were stalling. The outboards fully trimmed in are -19° off center. I think this was affecting the float level / fuel delivery / possible flooding?
Finally got to the bottom of this. First the data.
The transom has a 15° angle.
The motor specs state a trim angle range of -4° in to 20° out.
So before we start, the transom angle has consumed 15° of my 20° trim. The motor will NEVER trim up. Poor matching of the outboards to the transom /...
Apologies for the late response had my three grandbuddies here for 10 days and they consumed all my waking hours. Get them but once a year.
The date was my bad. That should have been 2006. The motors were manufactured in 2005 but registered as 2006 when sold with the boat.
My outboards are...
Spoke with a Yamaha agent yesterday a.m. He says that the integrated ram has an area deemed to be the trim part. He surmises that the transom angle is too great and that the trim reaches full extension and moves into the tilt part and then does not have sufficient power to overcome the water...
Morning, I am located in South Africa so it would be a motor destined for Europe I would have thought.
It is a 2 cylinder, 40hp, with both electric and pull start and they claim Power Trim and Tilt.
On the PTT I note that there is only one hydraulic cylinder that is permanently connected...
I had similar on my 130hp. It was the oil level sensor in the remote oil tank. One of the terminals had corroded in the 4 pin plug and would make contact intermittently.
The motors will not trim up when under load. Are perfect when not under load. Tearing my hair out. My bow is too low in the water and clearly not efficient. I have had this issue since I acquired the boat.
Seals Replaced
Fluid topped up and bled.
Both motors trim and tilt in both directions...
