cesar mini cat and yam 20 autolube

[Supremesoundz]

hi iv got the above and just wanting some prop advice its runnin the std 9 7/8 by 10 1/2 prop on a yam 20 hp 2 stroker

ive seen on the web ppl run these with the engine raised trimmed right out on the pins with a toatsu 18 and 30 hp..... one had a 13 st/st prop the other a 15
one was hitting 76kmph the other 54kmph mine only seems to touch 27 mph trimmed out one notched any more than that i just get a load of prop slip and bow lift

i think ive seen some where i need a semi cleaver as of the shallowness it runns

any ideas ppl

I probably have a couple of props of a suitable size you could try. I'll have to check whether they will fit.

[Supremesoundz]

that would be awsome im thinking id prob need a 13 pitch as the 18hp i saw also had a 13 id just get a lil bit more holeshot but im completelty open to suggestions as i dont have a clue

[Techteam]

I am not home till next weekend but I have 2 Cleavers at around 9 3/4 by 13 ish a couple of round ears that are progressive up to about 15 I'll have a look as you may have to get them bushed but we'll see.

[Supremesoundz]

ideal let me know when u can and thanks for ur help

[Supremesoundz]

did u have any luck looking @ the props

[Techteam]

So I have nothing that you will not have to rebush but there is a 10 x 15 cleaver and a 9 1/4 x 15 Round Ear.

[Supremesoundz]

ah so both of those would need rebushing? i think 15 would be a bit big not sure
