Pacific coast Datsun Posted October 30, 2018 Author Report Share Posted October 30, 2018 The boat may get 1 last run on the river tomorrow then she gets stored away for the winter. Our weather turned a few weeks ago & the water levels in the river are a bit lower now. Quote Link to comment
Pacific coast Datsun Posted April 8, 2019 Author Report Share Posted April 8, 2019 The 2019 Bullhead city river season has begun. Took it out last Wed & she ran ok..replaced the fuel filter & ill check the spark plugs tomorrow. I also now have the original engine bay cover ! It needs some fiberglass repairs then paint but nothing major. This is a pic from last year... 1 Quote Link to comment

It sure is !! It does have a little more top end speed & I'm getting a full throw on the throttle cable now. It doesn't " kick in" like It used to when the 2nd barrell used to open..now it's a smooth acceleration all the way through. 2 Quote Link to comment
Charlie69 Posted May 16, 2019 Report Share Posted May 16, 2019 So I take it you like the Sync link? Quote Link to comment

Pacific coast Datsun Posted July 27, 2019 Author Report Share Posted July 27, 2019 (edited) Since my last post we've been taking the boat out every Sunday & she's running great. About every 5th trip i top off the oil...im guessing the rings are going bad & I'm getting smoke coming from the filter on the valve cover breather.

Pacific coast Datsun Posted September 26, 2019 Author Report Share Posted September 26, 2019 Ok update time. Last time out the motor developed an internal knocking noise & I lost all power. I'm guessing one or more of the bearings went out. Over the winter it will get a full rebuild & I'll get the engine cover repaired & mounted. 2 Quote Link to comment
Pacific coast Datsun Posted May 1, 2020 Author Report Share Posted May 1, 2020 Update time. The motor is at the shop getting a full rebuild. & I've got the front part of the jet apart for 2 new bearings + some cleaning & painting. I'll try & get some pics up soon. 1 Quote Link to comment

john510 Posted June 7, 2020 Report Share Posted June 7, 2020 I'm a boat guy myself and love that thing.I have a question,what kind of cooling system are you using ? Raw water or closed system with a heat exchanger ? And how is the water pumped to the block and head ? It looks like there's no water pump on the motor. Quote Link to comment
jagman Posted June 7, 2020 Report Share Posted June 7, 2020 If you are going to run in salt water you need replaceable zincs in your cooling system otherwise your aluminum parts then the iron parts will begin to erode. Quote Link to comment

The boat is propelled by a jet & it sucks water right from the river via a supply line next to the impeller that connects to a fitting that mounts where the thermostat usually goes. Water is also fed into the exhaust for sound deadening. Edited June 8, 2020 by Pacific coast Datsun . 2 Quote Link to comment

Our boat will never run in salt water. We live 1 block from the Colorado river 😎 3 Quote Link to comment
DanielC Posted June 8, 2020 Report Share Posted June 8, 2020 "Water is also fed into the exhaust for sound deadening." Water is fed into the exhaust to keep it cool. The sound deadening is a byproduct 1 Quote Link to comment
