    Need to determine best prop for weird setup

    Thanks for the link! So I double checked in the manual and it only says for the 4.3gl a/b/c/d that the Idle timing should be 1° BTDC. In theory if I have it set to that degree at idle should it be correct when it’s advanced at 2800rpm? Let’s just say that it’s not around 25°, should I change the...

    Now that ignition analyzer that doesnt do timing as well right? if i get a modern timing light with a tach also on it that will suffice? like this one for example...

    Need to determine best prop for weird setup

    OK your probably right, something else might be going on. 17" 3 blade 4000rpm. 21" 4 blade 3600rpm. I agree should have seen more change than that based on the 200rpm per inch of pitch rule. I havent checked ignition timing in that depth before so im not sure how. Ive only ever gotten cylinder...

    Need to determine best prop for weird setup

    Thats news to me! Thanks for pointing that out before I go in blind with someone telling me its in the upper and all the lowers are standard rotation

    Need to determine best prop for weird setup

    I haven’t verified the tach with a shop tach. The speed I was confirming with gps so I know it’s accurate. I might have a line on another upper Volvo gear housing with a better gear ratio so I’ve temporarily stopped thinking about props until I hear back

    Need to determine best prop for weird setup

    I know changing gear ratio back to around 1.8 or even 1.65 would be more ideal but its either hard to find or costs way more money than i want to spend. im just focusing on getting my rpms correct so i dont grenade my engine. Ill have to suck up the fact that my boat is suppose to do 46mph but...

    Need to determine best prop for weird setup

    How much effect does the diameter of the prop change the rpm? Think if i swap my 15x17 for a 14x17 or 13.25x17 it will bring my rpm up from 4000 to 4400? or would i be better off trying a 15x15 next? thanks

    Need to determine best prop for weird setup

    I looked back on a video and its sitting at 4000 / 4100 with the 3 blade 17 only hitting 33mph ish

    Need to determine best prop for weird setup

    1998 Four Winns 180 Horizon RX 1998 4.3GL Volvo Penta 1.51 gear ratio Hello! I have a boat that’s had its outdrive unit swapped out with one I’m assuming use to be in a v8. As per Google my 4.3gl should have around a 1.80 gear ratio outdrive but I read the tag and it’s a 1.51. At WOT I’m only...

    Volvo 4.3 Strange dipstick readings

    I solved it! It’s all the right parts but is routed incorrectly. Someone has routed the tube beneath the engine mount instead of above it like it’s suppose to be. Hope someone else can benefit from this experience. I’ll attach some pictures of how it’s suppose to be ran to compare. Thanks!

    Volvo 4.3 Strange dipstick readings

    Ok thanks. Regardless, what’s the best way to re-mark the dipstick at the right oil level?

    Volvo 4.3 Strange dipstick readings

    Hey everyone! I got a used boat with a 1998 Volvo Penta 4.3GL. Checked the oil and it was a good 1.5” above the Max line when cold. Went to do an oil change and only sucked out about 2.5L of oil through the dipstick including oil I dumped out of the filter. Now I’m confused. There seems to be...

    Outdrive Pressure test Question

    Nice I’ll check them out. Just whipped up a prop shaft bearing carrier tool. It’s not the prettiest but I’m just going for functionality 👍
