1990 BFN

Hey Fellas, just getting time to post our latest ride. This fall a local guy (knew him from my N3 Days and the river) had for sale a brochure color scheme 90 BFN.

The boat has been maintained mechanically pretty well other than a junk Dizzy and dirty neutral. Structurally and interior wise it's in great shape just needing the observers seat base and drivers seat base replaced.

Winter plans include a transmission rebuild/trailer refurb for function/wet sand buff and decals.

I will update this thread as we make progress but here are some photos from when we picked it up. Sorry they aren't the best.

The motor runs exceptionally well despite having a locked distributor timing mechanism. It went 50.0 on GPS with the tach showing around 4950.00 running Tim's spare 430. GPS confirmed speed by a Garmin Etrex not an I phone app. Mid range and hole shot are so good I would be reluctant to step up to a 1598 for an extra mph up top.

3 and one extra I ripped in half.

Very nice boat Zach! Great colors. Looks to be in really nice condition.

Have you done a transmission yet??   If needed I can assist. ( I only do a partial rebuild cause I don't know what a full one is yet, still waiting )    Duane

Ah.......................A trip down memory lane Duane

Duane,
I thought we covered it but maybe you missed it. I sure miss things a lot probably due to my ADD!!! Beyond clutch packs, bearings and seals, the only other thing I feel is needed is checking the health of the pump. There are specs on pressure but the trans needs to be assembled and turning to use that. I know Eric used to chuck his rebuilds up in his lathe to check. The only other way is to check pump clearances and I have yet to find Velvet specs on them. I do know with a geared hydraulic pump .0005 at the teeth and the same between the gears and housing is a rule of thumb.

Zach,
Nice!!

I hook mine to an old riding mower with a horizontal shaft and an electric clutch.

A splined hub from an old damper plate welded to a pulley and a v belt make things go round.

Depending on where I mount the transmission, I can do righty's and lefty's.

Due to the "hackish" nature of this setup I usually do it in the backyard under a shadetree at night

But.................it works

I am looking forward to seeing that boat up here on Deep Lake sometime. Ought to be looking like brand new with your experience and connections!

Pete would be proud of my alignment job Rubber belt with a little twist of sorts, it's a good thing I don't have to run it very long to check pressures. Transmission angle is a little funny too, to get things lined up pretty close.

Chris,
Here's Ken's guide to his 3" alignment.

And more importantly, congrats Zach!

The frozen timing in the distributor - how it is running that strong without a decent amount of advance? Surprises me.

I don't think it's frozen in the block "locked distributor timing mechanism" I think it's either stuck in full advance or it's stuck in the opposite

Or maybe Zach sits in a jump seat with the motor box off and manually rotates the distributor to get max speed?

Nice Find. I love the color scheme. Does also seem to be in great shape.

Spec sheet would be nice but like you, I have not been able to come up with any.
Future thought:   If Zach decides to install a new pump we would be able to check new dim's against used pump dim's. Pumps are really not that expensive. I did do a visual on my pump components and could see no wear marks on gears or housing. ( FWIW).
It would be nice to set up a pressure test fixture to check the relief valve also.
