On a Yamaha 300 trim tabs, the larger cylinder attached to engine is leaking at the seals. Can you just replace the seals and not the whole sub assembly to repair this? Thanks and love the channel.
Hi Brian, yes you can replace the seals only, however I’d advise to also replace the cap if you see it has some corrosion on it, it really helps the seating of the seals and ends up being a better job. Send me the serial # if you need help in getting the part numbers. Take care and thank you for watching.
First, thank you for these great videos. I have twin 2020 Yamaha 200 HP engines with trim motors 63P-20 9G-1116 on the body, one of which is very weak sounding and slow. I finally diagnosed the issue. Air is getting into the system somewhere. There is no fluid leaking. I relieve pressure on the side screw and as I open the fill plug air is spewing out. Also, the fluid that eventually comes out is laden with air. Mine has a plastic fill plug with a rubber washer. I seal everything up and the trim motor work wonderfully for a short time and then I need to go through the same step as mentioned. Any ideas where the introduction of air could be coming from when at the same time there is no fluid leaking? Thank you.
Hi Heinrich, I truly doubt there is an air leak in these units, if there were, your fluid will look milky, sing there is water leaking in. The foamy fluid you see on your unit is not because of an air leak, but the use of the wrong fluid, to avoid foamy fluids make sure you use a non detergent hydraulic fluid, ATF is a detergent fluid and will cause foamy like fluid. Also make sure you add fluid with the unit all the way up, then after 2 or 3 cycles up down, bring it all the way up again and add more until fluid flows out the fill in hole. Hope this helps. take care.
@us4marine Thank you for taking the time to respond. Actually changed the fluid even before receiving this response from you. It was pretty dark and almost immediately the new hydraulic fluid was as dark. Ultimately, the trim unit stopped working altogether. Turns out some interior seal failed and was allowing the fluid to get up into the trim motor. I had just purchased the vessel about 10 months ago and after messaging you I discovered by chance that the previous owner had an extended warranty that he never advised me of. I lucked out and the whole unit was replaced by Yamaha. Thank you, though, I look forward to your future videos.
Hola! Tengo un problema con mi Yamaha 115 nuevo, luego de andar un rato la empieza a tirar combustible por una manguera que está al lado del testigo de agua... He leído que es un desfogue del carburador... Anteriormente habíamos quitado la cabeza del motor para cambiar una pieza del bracket. Agradecería muchísimo si me pudiera ayudar. Anteriormente usted me había ayudado a quitar la cabeza del motor. Saludos!
Hola Matias, estoy un poco confundido, dices un Yamaha 115 NUEVO ? y luego mencionas carburador ? También no sabría a que manguera te refieres sin algún apoyo fotográfico. Un saludo
Perdón por explicar mal, el motor tiene 100 horas es el modelo nuevo, hace poco le hicimos un cambio de pieza en el bracket por los que tuvimos que levantar la cabeza del motor y desarmar. Ahora lo que me está pasando es que al usar el motor durante unos 5 minutos aprox la manguera que viene del VST (separador de vapor) comienza a tirar combustible. Estoy pensando que puede ser por exceso de presión o algo así. No puedo enviar foto por comentarios de UA-cam pero si tuviera su correo o wsp podría mostrarle que manguera es. Muchas gracias
Remove the dowel from the tilt ram, remove the 6 bolts from the trim unit and pull the whole trim assembly back so you can service it. Remove the retaining clip from the manual release screw, then replace manual release screw with a new one. (Make sure you're ready to catch fluid with a pan underneath)
Another excellent video from your big knowledge. Thank you for share it. Best UA-cam channel I ever see it.👍
Thank you Alvaro for your positive comment, really appreciate it. Take care 👍🏻👍🏻

manual release valve screw is stripped what should I do?
Remove the dowel from the tilt ram, remove the 6 bolts from the trim unit and pull the whole trim assembly back so you can service it. Remove the retaining clip from the manual release screw, then replace manual release screw with a new one. (Make sure you're ready to catch fluid with a pan underneath)
Port side stern scupper is upside down
Thank you. Take care
