Hi I check in the archives as to which fluid should be used in the trim and tilt... I have leak from the fill screw .. o ring time..( yet another problem with this SPL... ) Its a little confusing....... ie.... tranny fluid or 20w engine oil.... I have noticed the fluid is red thus tranny fluid.... but as stupid as this sounds... does it matter between the different tranjy fluid such as Dextrom mercon etc ..... ?? Or should I drain it and use oil???????
