Leaking Tilt Actuator 70EGLT

[Yotabear]

Any recommendations on repairing or replacing tilt actuator on older engine that I bought used several years ago. Ive been maintaining the engine and runs well but the tilt actuator started leaking several weeks ago after I seviced it with a non yamaha brand oil. It worked fine for a while but started slowly leaking after a few weeks. Manual stated to perform full service and bleed when using other brand fluids. Shall I still try to do the full flush and bleed or is it bad seals because of an older engine? Reading an earlier post from the past a seal kit with special tooling was recommended any one know what special tooling was in the kit?

Thanks
